Abbey Sinclair is no ordinary teenaged girl. This 14 year-old genius has an IQ of 165 (yikes!) and her brain thinks in terms of equations, probabilities, statistics, and scientific truths. But when she and her brothers discover a portal to parallel universes crossing the boundaries of space and time, all that she has learned about the Derivatives of Displacement will be challenged as science and witchcraft collide in this fantastic thriller.

Jennifer Ellis wastes no time diving into the action. W

Sometimes when I’m reading I am torn between what I think and what would my 14 year-old self think. This is one of those books. My adult self is pleased to find a book that is full of both correct and well-imagined science, an enthusiastic young female scientist, and a great and unusual adventure. I wonder how 12 year olds will react to Mark, who plays an important role and is delightfully displayed with all his autistic quirks and fixations. I think my 14 year-old self will be wrapped up in the ...more
There are only a few reviews for this book and most of them start with "the author gave me a free copy of this book to review". The other reviews sound suspiciously like they are friends of the author :-).

Let me start by saying I don't know the author. I was definitely not given a free copy of the book by the author (I think my reviews are too honest to get books from authors :-P) so I guess I am independent. With that being said, each person is different so someone may love a book I don't. This

This was a great paradox! What a great fast read and a way to travel time without war, blood, aliens or any paranormal type beings. I was very surprised with the way the writer wrote about this in and out of time book.

Abby, Simon and Caleb, the three main characters, are young teens. The story is a mystery/time travel story.

I would definitely recommend this book to a teen or adult that likes this genre.

(I received a free e-book edition of this novel in exchange for a review. This does not in any way influence my opinion of this book. As a bookseller, it is important to me that my reviews are completely honest, as many of my customers have access to my reviews.)

"A Pair of Docks" is an excellent sci-fi read for ages 9 to 99! It is completely appropriate for children, containing no material or language that parents would object to, yet compelling to read as an adult. The story is well-written, wi

This one is for young readers 9-12 who like mystery, magic and time travel.

A Pair of Docks is a time travel adventure centred around a group of kids (the Sinclair siblings) who stumble upon a magical portal, which leads them to an unimaginable place. That place just happens to be right where they started, but in a different time. The story is focussed on the main characters (the kids), with parents etc secondary to the main plot. Their mom is running for Mayor and her story is quietly told in t

Elements I liked:
The writing style really kept you up to date on the story, and it helped you focus on what was happening. I truly felt like I was a part of the story. I have never experienced anything like the storyline in this book. But, I really liked it. It was interesting and kept my attention.

I received this book from Jennifer Ellis in exchange for a fair review. It starts out a little slow but takes a hold on you quickly. By the middle of the book I was having a hard time putting it down. I think it starts off a little slow so that you really get to understand the three main characters. It is really hard to figure out where Jennifer Ellis is leading with you with her story right up until the surprises at the very end. She really reels you in and keeps you guessing throughout the boo ...more

If you hadn't figured it out from the name of my blog, I'm a little bit of a math geek. Just a little bit, though – I'm smart enough to be interested, but not quite smart enough to handle advanced concepts. (Maybe I could have before I had kids and my ability to think was replaced by the ability to change a diaper with one hand while refilling a sippy cup with the other all while singing "Twinkle Twinkle Little Star" twenty times in a row!) I actually double majored in elementary education math ...more

First, this is an engaging read that moves along at a fast pace and keep the reader turning pages. It is well-written and thoroughly edited, and the plot and the world the author creates both hang together well. That said, I have a couple of issues with the book.
My first problem is not necessarily a flaw the book: I share Abbey's discomfort with the idea that witchcraft could be real. To put it another way, I don't like suggestions that the laws of math and physics might not hold for everyone in

The book’s cover is very attractive. It captures the nature’s beauty and at the same time seems mysterious. The different shades of green is just so gorgeous. The creeper like font used for the title follows the same natural theme as the rest of the cover. This is such a well designed cover. It’s one of my favorites of all time.

The story’s main protagonists are three siblings namely Abbey, Caleb and Simon. In the first chapter itself, the mystery begins. It pulls you in right away. There is a se

After reading a blurb I was amazed. Physics? Time Travel? Sounds like my thing!!!

And I was a little dissapointed.

Let's start with the title. Loved it. Great play on words.

Characters? I was expecting more, actually. I mean the author didn't really convince me that Abbey is such a genius, it's obvious that she knows stuff, but even for a second I haven't thought that Abbey migh

Mystical stones, coded emails, time travel, and guarded secrets combine to make A Pair of Docks an action packed consuming read.

Abbey is a brilliant 14 year-old science fanatic with an IQ of 165 who spends most of her time in the physics lab at the high school. Abbey has an older brother named Simon, who has recently been acting very secretive and a twin brother named Caleb who is popular, especially with the girls. The day Abbey witnesses Simon sneaking off into the forest she enlists Caleb to

This book is categorised as a Children’s book, but please don’t let that put you off. Given the complexity of the story, the layering of the characters and the pacing, it feels far more like a YA offering to me. I thoroughly enjoyed this one. The time travel element has been done very well, with the initial hook pulling the reader into the story and then learning the very rich backstory as the adventure continues. The story progression and overall pacing are deftly handled.

This was a bit of an odd book. The first sentence of the book, made me want to just put the book down, and forget about it. I was pretty darn sure I did not want to read a book that started with that sentence.

I continued to read it, all kinds of "crimes of writing" came up with it. The way the protagonist was written there were "facts" stated about her, which really did not come through the way which she was written.

After a bit, I decided that I was reading it as entirely the wrong genre. I tho
I received this book through a Goodreads First Reads giveaway.

It took me a bit to get into this book. I found the main character a little hard to identify with and Mark's character was a little disruptive during the first part of the story. But by the second trip through the stones I was definitely getting into the story and by the third trip I was hooked.

I would have liked a little more character development. There was obviously some friction between the siblings and I wouldn't have minded know

Exquisite, marvellous, fantastically scientific.
I adored reading every bit of this book, including night shifts and this didn't happen since the time of Harry Potter.
Fresh look at time travel and the eternal dilemma of fixed unalterable future with annexed paradoxes versus incipient futures.
All this seen through the curious eyes of Abbey a geek teenager boarding to nerdish, Simon a computer genius nearing asocial and Caleb the more amorphously flowing of the three. I found it incredible the cre

A Pair of Docks is a book about Abbey, her twin brother Caleb, and their older brother Sinclair. Abbey is extremely intelligent. She has an IQ of 167! The siblings discover a route to what they believe is the future world.They discover that others know of this secret passage way. They find themselves in danger while trying to disseminate the things they know and how they work. This book is absolutely wonderful. It reminds me of A Wrinkle in Time but for an older reader.

I really enjoyed this book. From the beginning, it was hard to put down. The story had a lot of twists to it and kept it very interesting. The characters in it kept you involved in the story, never knowing what would come next. The fact that there were other worlds and time periods in it kept you wanting to read more of it. It was very well written and I can't wait to read the next book. ...more

With smooth, flawless writing, Ellis takes readers on a time travel adventure that is both clever and captivating. "A Pair of Docks" contains hints of dystopia and witchcraft that is scientifically grounded - concluding with an ending that is satisfying but not complete. I'm definitely looking forward to book two of The Derivatives of Displacements series. ...more

It is definitely a young teen book, and as a parent of very avid young readers i try and proof what my kids will potentially be reading. I loved the dynamics between the siblings and how real that it seemed. In would recommend this book and anything so far written by this author.

Derivatives of Displacement... This made me think the book would be a scientific approach to time travel (of course only theoretically). A Pair of Docks is about time travel. One of the main characters is a girl named Abby who is very scientific. This is evident in her thoughts throughout the book. The author includes scientific

I thoroughly enjoyed this book. First of all, I enjoyed the characters and the combination of fantasy and sci-fi. In addition, I enjoyed the writing, story telling, and description and found the pacing and plot engaging. However, I did take issue with a few plot and character elements as described below.

First of all, the main character has a supposed IQ of 175 however, there are a number of times when she doesn't react or respond appropriately for this IQ. I understand that she

I haven't finished this book. In fact, I haven't gotten very far in this book at all. Not that this is not a good read, I just haven't gotten far enough into it to be able to say one way or the other. My problem with this book is that it is too sci-fi for my pleasure reading tastes. I like sci-fi as a splash of flavor in my fantasy reading. Too much sci-fi and my brain starts shutting down. So how then did I en

It took me a little while to get into the book (part of that could be that I'm a distracted reader these days with the toddler around) and to start to like the main character, Abbey. At first she seems like just a brain walking around in the body, rigidly wanting to sticks to rules, scientific or otherwise. But as the book progresses, she starts to bend a little and by the end of the book, although she hasn't thrown out her belief in science, she comes to realize that the world contains things t ...more
