"The planets were moving towards each other in the night sky when Isaac and Thea first met.’’

Yes, this is a wonderful combination of meaningful science-fiction and a charming relationship between two bright scholars. Yes, I enjoyed it immensely. Don’t worry, no aliens abducted me:) It is just that Khan’s writing is absolutely brilliant.

Thea and Isaac meet as undergraduate students in a lovely evening when a magnificent natural phenomenon takes place in all its glory. A few years later, Isaac

Katie Khan is back with her sophomore book, The Light Between Us and it's as greedy a book reading pleasure as her first release Hold Back the Stars which I had the immense pleasure of reading last year. Click here for that review.

And what I mean by greedy is that this is a book you will simply want to gobble up as quickly as you can!!! Her writing is so wonderfully captivating but most importantly of all... She tells amazingly compelling stories!!!

Decided to rate my own book, which is something I never do, to balance out the 3-star rating from a lady in Illinois who meant to review 'The Light We Lost' (because my novel wasn't even finished when she gave it 3 stars, and she reviewed 'The Light We Lost' 45 seconds after rating mine). Ah, goodreads, what fun we have.

THE LIGHT BETWEEN US publishes August 9th in the UK! It's a story about a scientist convinced she can establish time travel... with one major glitch.

The Light Between Us by Katie Khan is a story about time travel and friendship.
Thea and her friends foolishly attempt a time travel experiment that goes terribly wrong and one of the friends Rosy is now missing. They are trying to find her or a way to bring her back.
I would like to thank NetGalley and Random House UK, Transworld Publishers for my e-copy in exchange for an honest review.

I have mixed feelings about this book - there were lots of aspects that I really loved...I love that Thea gets kicked out of Oxford for trying to prove her time travel theory. I love that she's a bit odd. I love that she's using crystals to fragment light to make her time travel theory work. I also really liked her friendship group, and the support they give her.
It's a very readable book - once I started reading it I raced through in just a couple of evenings.

But, as with her previous book, it

I found this to be a fascinating and touching sci-fi/romance that was full of smart female characters who showed ambition and determination and that makes for a much more pleasurable reading experience!

I haven't read the first book from this author - Hold Back The Stars - which is to be made into a movie, and I can see the film studios grabbing hold of this book too as it had so many elements that would make it perfect for adapting to the big screen!

It's the story of Thea and Isaac who are firm

I had high expectations for this book (I gave Khan's previous book, Hold Back The Stars, five stars), but I gotta tell you I kinda hated this one. This felt more like three interconnected novellas than a novel... Or at least, I think Khan had three distinct stories to tell:

First, there’s Thea, who’s just been kicked out of Oxford for messing with time travel in pseudo-scientific ways that would never get past the academic phase, let alone experimental. Second, there’s her friend Rosy, who’s

If two books establish a pattern, then it's safe to say that Katie Khan's books are difficult to rate. There are parts that are absolutely astonishing in their awesomeness, researched to sound as realistic - or at least as possible - as possible. These are the parts you want to shout spoilers about and shove the book into everyone's hands.

But there are other parts of the book that you're just not interested in, or you disagreed with the author's choices for storylines or focus.

Started strong and intriguing, but the more it went on, the more it lost me. Too much explaining the science behind it all (I want a good story, not a science essay), and dangling back stories/character secrets for too long without a reveal. Still curious about Katie Khan, as I really liked her debut, which was unexpected and unique.

I'm somewhat torn between 3 and 3.5 stars because there were parts I really enjoyed but also parts during which I was confused or a bit bored. The Light Between Us is a creative and beautifully written book, but it couldn't fully grip me or hold my attention.

Good things first.
I loved the idea behind this: romance with a hint of science fiction makes for an interesting mix. I also enjoyed the writing style. The author uses a very fluent yet poetic language, I found the book to be very

Look I'll be honest - if I was watching TV and a film about time travelling came on, I would instantly switch over. For me personally, the whole science fiction, portal, time travelling sorta stuff has never been my cup of tea. Until now. Yes, yes, I know. I am as surprised as you are. However, my feelings on the theme of the book have changed due to Katie Khan. Whether I would find another fictional novel containing

Thea Colman and Isaac Mendelsohn met on a cold night at St Catherine’s College in Oxford to witness a great celestial event. Five planets aligned and under a blanket of stars they’re fates aligned too. He was studying psychology, philosophy and linguistics. She was armed with a theory to prove time travel possible and a determination to succeed no matter what. Instantly a friendship sparked between them. A bond unlike any other.

Some years later and they have gone their separate ways. Their

Katie Khan has a habit of leaving me with a HUGE book hangover; it took me a week to get over her debut novel (Hold Back the Stars) and six days after finishing The Light Between Us I am still a little punch drunk! Katie's writing is absolutely beautiful and I wanted to savour every word and relish in all the emotions.

A desire to succeed in her field and regrets from the past result in Thea's attempts to control time. She is aided in her quest by fantastic group of female friends (Rosy,Urvisha

To find a novel as enjoyable as The Light Between Us is almost like a syzygy - it happens once every ten years. Khan’s ability to portray the trials of time travel and long lost love whilst simultaneously highlighting strong female friendships is a masterpiece in itself.

The story follows Thea, a grad at Oxford, who is studying physics. Fueled by her interest for time travel, Thea wishes to further her study of it but is renounced by her professors. She secretly builds her own ‘time machine’ - a

I read this book in 2 sittings, completely addicted to this storyline and how it was written in such a captivating and believable way. Katie has done it again, creating a fantastic and unique plot with characters that I loved, flaws and all. I may even be a little in love with Isaac. Also... KATIE! I CAN’T BELIEVE YOU PUT ME IN THE ACKNOWLEDGMENTS! I’M SO HONOURED, I EVEN CRIED WHEN I SAW IT! THANK YOU SO MUCH!

Overall, a brilliant book that I will be reviewing in more detail over on my blog:

The Light Between Us is a sci-fi romance done right. Thea is a physicist at Oxford who thinks she’s close to figuring out the secret to time travel - but her experiment goes wrong and she’s kicked out of Oxford. I don’t want to give too much of the plot away but it features some fantastic female friendships (though poor Ayo seemed under utilised as a character and I’m not sure what she added to the plot) and a lovely romance and lots of science, but very accessible science. I loved Katie Khan’s ...more

This is a book about 4 women friends. They are academically gifted, gorgeous, and fearless. It is so good to see such positive young female role models in a sci-fi novel. Then there is Isaac Mendelsohn, a credible male lead and the heroine's love interest. There are many reviews of Katie Kahn's book outlining the plot so I am not going to elaborate on what actually happens. I just want to make a couple of points.
Firstly, I like the way the science is handled without too many complicated,

I was drawn to The Light Between Us as soon as I set eyes on that beautiful cover and having read the book I can confirm that it's just the perfect choice for this touching and unusual love story. Thea and Isaac become friends at Oxford University but have drifted apart over the past few years. Isaac believes Thea has become too single minded to the point of obsession while she resents what she perceives as his lack of belief in her work. She fervently believes she can prove time travel

Conflicted by this one, I really enjoyed parts of it but certain aspects just didn't make sense and overall it felt unresolved.
I love the mixture of science fiction and romance, and I loved her first book. I think maybe time travel is too speculative for it to work easily.
Fingers crossed for the next one.....

I was really grateful to receive a proof copy of this book from Hannah Bright at Penguin Random House.

This is Katie's second novel and I must confess I have had her on my giant TBR pile for a while having never quite got round to reading her debut novel "Hold Back the Stars".

The book starts with Thea and Isaac our main characters who meet at Oxford University in 2010. Then jumping forward to the present Thea is still at Oxford as a post-graduate. We come to learn there's been a breakdown in

Oh Katie Khan, what are you doing to me?! First you write Hold Back the Stars which 18 months after reading I still frequently think about and now you have filled my heart with The Light Between Us.

The Light Between Us is about two estranged friends, Thea and Isaac, who are brought back together when she discovers how to travel through time. Thea is studying for her PhD at Oxford University and despite the Physics Department believing that her theory is a waste of time she has doggedly

The Light Between Us is a contemporary romantic story with a unique sci-fi slant to it. It sounds confusing and bizarre, but it’s not. Think along the lines of The Lake House staring Sandra Bullock and Keanu Reeves, which is such an endearing film. The plot revolves around female scientist, Thea, studying for a PHD in Physics at Oxford University, who is secretly experimenting with time travel. When one of her friends, Rosy, goes missing after the experiment it seems the impossible has happened ...more

Thea and Isaac have been friends since university. Their attraction is undeniable but their timing awful. The main issue though is that from the start Thea has been obsessed with the idea that time travel is possible and her brilliant scientific mind has found a way. When an experiment goes wrong and one of her best friends and Isaacs exes goes missing they are drawn together again to search through time, not just for her but maybe for each other too.

Warning. Do not read this book if you are

Katie Khan's debut novel, Hold Back The Stars, asked us to consider the fates of two people tumbling through space, with limited oxygen, as they reflect on their relationship and try to save each other. If one could survive, what would life look like without the other? The result was a powerful examination of love with an ending that left me in tears.

Her new novel, The Light Between Us, asks us to consider a love that never happened, for one reason or another, and what might be different if the
