“Let me discover you. Slowly. Over time.”

I am obsessed with this ‘Law of Physics’ series! Time is the third and final installment and it was everything I wanted. I’ve read all of Penny Reid’s books, and after some serious deliberation, I have to say that Abram is my #1 favorite of all her heroes. I’m sure that has something to do with why I love these books so much!

Abram and Mona finally have the chance to be together, after a long and tumultuous start to their relationship. But do

If time is the result of gravity shaping or warping reality—which it is, which is why clocks tick faster on a mountain than at sea level—then what impact do heavy, weighty feelings have on time? I hypothesize that sadness slows time, and happiness does the opposite.

In this last installment of the ”Laws of Physics” series, Abram and Mona are struggling to find the balance between their personal and professional lives. Now that the truth is ou

When I read a Penny Reid book magic happens. Those are not cookie cutter stories but spellbinding and unputdownable treasures, her characters so entirely endearing that I wish they were real so that I could be their best friend. Mona and Abram are thieves - they up and ran away with my heart. And let's not forget Penny Reid's genius thoughts that spi

What a fun ride it was! They had their differences but I loved how they talked about it and understood what the other need.

A sexy and emotional finale for Abram and Mona. Abram soared so high up the swoon-o-meter in this book everything exploded. Or melted. Or fainted. Or all of the above. The point is Abram is quite possibly the swooniest swooner that ever did cause swooning.
Issues raised from the previous books were dealt with beautifully by all of the characters, giving Mona the closure she needed about the past and clearing the air between her and her siblings. Of course, Abram was there every step of the way su

Mona DaVinci is a brilliant, world famous scientist who is used to being in control. She analyzes and plans everything, except falling for a sexy musician who makes her feel alive. The problem is they are on different paths leading two separate lives with conflicting schedules. She’s a genius physicist and he’s a talented rock star. While she’s doing research, he’s touring. As the frontman of the band Redburn, Abram has a responsi

Abram owned me! He grabbed a hold of my heart when this story was put into Motion and he made sure not to let go when he refused to leave any Space between himself and his love. When he and Mona finally found some Time, he decided to finally claim me. And I was oh so willing to be claimed!!

Abram was perfection! I must admit that as much as I've loved Mona, she irked me a bit in this book. Abram's love was so all-consuming that her love felt like an add-on. It wasn't as powerful or as moving

Favorite Quotes:

Being with you is like living in a song.

Give us a chance to win big, and also fail spectacularly.

Nothing happened, and yet— and yet, I carry it around with me, empty luggage, and I have no idea why.

Please don’t waste energy on this. Haters gonna hate, idiots gonna procreate.

Do I like it? Does each action have an equal but opposite reaction? … Sorry. Newton. Not the fig kind.

I was much too impatient to wait 2 extra weeks, especially since I knew the Apple edition released early—and I'm so happy I didn't wait! I have devoured (literally devoured; couldn't put it down once I started and waiting between the books was agony!) this series since the first book and this one was no different.

OMG, the feels in this book! I could go on for hours about Mona and Abram, but I won't. Just know that the third book in the series is perfection and the entire series is a can't-miss

Time is the conclusion to Mona and Abram's story that I have been dying for since I started their journey. They've had a pretty crazy time over the past two books and it didn't get any less insane in this one. They're two completely different characters, which is what made them so perfect together, but also made it hard for them to be together. I was rooting for them, though, and I couldn't wait to see what kind of ending they would get.

I wasn't disappointed at all

I don't know why I didn't love this book. I thought for sure after reading Space, that this would be another 5 star read but unfortunately the entire time I was reading I just felt "meh" about it.

I think when it comes down to it, I wanted one thing from this novella but I was given another. In my head, I wanted this novella to be about them in a relationship and working through that. Which, technically this book was that. Except it was more about working through a long distance relatio
Welp, that took a turn. But feel free to ignore this. This is definitely a me problem. Carry on.

More than 5 stars!

I devoured this story with everything in me. Why do all good things come to an end? Abram and Mona are life. This book gave me intense deep feelings, and made me think. My heart went out to Mona, with the conflict that roared in her mind over what she’d been through at 15. I love how Penny showed us how she worked through it. Mona is a overcomer.

Abram on the other hand is bloody perfect! Downright swoony, and had the patience of a saint. So unbelievably sexy. I’m a sucker for

Well that was unexpected. In absolutely the best of ways. Whenever I read a trilogy I try to wait until the last book is available as I have zero patience and the worst memory but it's Penny Reid and I just couldn't wait. I signed up for the blog tour and promptly fell in love with Mona and Abram.

After the second book I was so happy. The identity deception was out and they were together and going to make it work. But OMG my stomach was a massive ball of knots worrying what was going to happen t

I already knew I had a Penny addiction before starting Laws of Physics, but not all addictions are bad... right?

I usually devour Penny’s books as soon as they’re released but I can’t deal with cliffhangers, so it’s been torture having to wait for all three instalments of Laws of Physics to release before I could dive in. Then again, it was absolutely worth the wait!

Penny has her own unique writing style, which I admire so much; her stories are always intelligent, quirky, witty and engaging
4.5 all the time in the world stars

Argh! I LOVE this story! Abram and Mona are purrrrfect!

“Ditto, Mr. Harris.”

Well if the whole is equal to the sum of its parts... I would have given this one another 4 stars. But that must not be the case, because she seems to have saved all the good stuff for last. Loved this one. I fell so in love with Mona in this book, even though I wanted to shake some sense into her half the time. That inner genius of hers finally started to develop the common sense she was lacking. Lovely series Penny. Ab

5+++++ STARS !!!

Let me just pause for a moment. This book, by far , has been the best book I have read this year (and maybe last year too). From the very first chapter I couldn't put down the book. Mona and Abram are just so imperfectly perfect for each other!
I don't know what else to write but I can say for sure, this series is my favourite of all the Penny Reid books I have read (and I have read them all!!) Do not miss reading it!!!

Penny Reid has done it again. Time was a "read it in one sitting because I was starving for more Abram and Mona" kind of book. The last book of the trilogy was so good that I didn't want it to end. I have loved every single book that Penny Reid has released. Every. Single. One.
Lacey (Booklovers For Life)
Loved this trilogy! Can be read apart from any of Penny's other series'.

Book 1: Probably my favourite of the three. The falling in love part, the character building, the set up. I loved both leads, and of course we have a fab quirky heroine.

Book 2: Oh the angst! I had a lot of feels with this one. The anger, the sadness, damn these two.

Book 3: Oof! I was on a bit of edge with this one. There were so many variables, i was waiting for something bad or devastating to happen. Thankfully it didn't! B
Angela (Reading Frenzy Book Blog)
I originally gave this book 3.5 stars, but I upgraded it to 4 stars after sleeping on it and here’s why. Motion, the first book in the Laws of Physics series, sets an infectious tone of both humor and tension. The second book, Space, is achingly emotional. Time, while very enjoyable, is not the gripping conclusion I was anticipating.

Mona and Abram are still incredibly endearing. Mona’s mind is a brilliantly logical delight, and Abram has the most tender heart imaginable. I adore them both. Their
And so it has come to this...

There's just something special about characters that make you feel so incredibly much so fast. Who make you happy when they are happy, or sad when they are sad, angry when something screwed up happens to them in the story, and so forth. And I have encountered a small amount of authors who are able to pull this off; Penny Reid is one of those authors.

Laws of Physics has got to be one of my favorite things Reid has ever written; I am a big fan of angst, and a well wri

The feels, not only in this book alone, but the trilogy as a whole are immense!

And they ran the gamut: sweet, swoony, frustrating, irate, heartbreaking, heart melting, gut wrenching and mind boggling...and these are just a few and yet it was all worth it as everything finally evened out and balance (of a sort) was a achieved (And, yes, I did consider attempting a “Mona-ish” style

Time is the third and final book in the LAW OF PHYSICS trilogy and in my opinion, this is the best book/series Penny has written to date.

There are so many things I want to say about this book but unfortunately, I don't think I can without adding any spoilers to my review.
What I will say is that I think Penny has written the perfect protagonists.
Yes, they have flaws and are by far not perfect BUT, what makes them so extraordinary is their bravery, honesty,

All the timeless stars. All. Of. Them.

This story. Man, it is so much. So much love. So much soul. So much depth. So much uniquely Penny.

In addition to an outstanding story and superior writing there are threads here connecting every series in the Pennyverse which, as a low-key obsessed reader, I adored.

This series in particular, and Penny’s writing on the whole is a genre unto itself. She has no true peers that I have found. The depth of story, the humor, the world building (yes, contemporari
