Private beach (…and boat).
Not so invisible girl.

Start your review of Heat (Elements of Chemistry #2; Hypothesis #1.2)
After the shocking ending of the first serial, I wasn't sure where Kaitlyn and Martin's story was going to lead. However, 'Heat' picks up right were 'Attraction' left off, so you won't be left hanging for long. In fact, this book featured one of the quickest resolutions to a big conflict that I've ever encountered. It was even a little anti-climactic for me, as I love the grovel.

That being said, I still enjoyed this book immensely. Kaitlyn never gets old. Her quirky, but endearing, antics kept m

Part 2 of Penny Reid’s Element’s of Chemistry is aptly named Heat. Things really start to heat up between Martin and Kaitlyn. They are still in the bliss of their perfect week together. After that cliffhanger from book one, we get to see what happened and why.

Martin and Kaitlyn both have stronger feelings for one another then they thought possible at this stage in their relationship. Kaitlyn learns a lot about Martin. Things about his past and family. Things that have shaped him i

Okay, I know what you’re thinking. Another five star rating from me, how can that be? Well, it’s pretty simple. Penny Reid continues to write stories that really rock my world. It is with such ease that she sucks me into her stories leaving me no other choice but to fall in love with the characters and the plot. In HEAT Penny continues with her wit and originality. In this one she gave just a little bit more.

That little bit more comes in the form of some pretty scorching hot and sexy scenes

I want you to stop for a moment and think back to the years of 18 to 22...with the demographics of Goodreads, it could be right now or many many decades ago...I ask you to do this because we all go through that stage and the intensity of it can be thrilling, adventurous and scary as hell...all at the same time. The core feelings of lust, love, and sex will always be the same... but depending on who we are and how we process things will guide our action

Whoever said Penny Reid can't write sexy better read this book because let me tell you something, not only she CAN but the sexy factor she rocked in this second installment of the Elements of Chemistry will absolutely knock your socks off.

Penny Reid strikes again!
You’d think because you knew about the cliffhanger you’d be able to manage and remain calm?

Pffff. Think. AGAIN.

Penny Reid did the unexpected once more, managing to break my heart in little less than 200 pages. Oh but she did it sneakily, you see. She let me me believe I had reached the nirvana first, then abruptly ripped it off of my hands.

I cannot even begin to express my excitement when I saw this hit my Kindle and was ready to jump right back into Katy & Martin's world with the second instalment of Elements of Attraction! And as the title simply puts it, Heat turns up the intensity between our duo and if anyone here dare says Penny Reid can't do hot and steamy, Y'ALL BE DEAD WRONG.

Heat starts off right where Attraction left us hanging. I collectively breathed a sigh of relief at the fact that Kaitlyn and Martin are still on and off for some hot R&R and explore their attraction to each other. And oh boy, did they explore.

Heat is an apt title for this book because this is the hottest book Penny Reid has ever done. Talk about explosive chemistry. Martin and Kaitlyn spent that one week exploring each other physically and emotionally but there's always that question

I think Penny Reid is a mad genius. I know that once I pick up a book from her I’m in for an amazing reading experience and with her one-of-a-kind sense of humor and sharp wit, her stories always hit the mark for me. It certainly rang true for book 1 in this series Attraction and to an extent it was also true for this second one; however I do have some reservations about this book. A big one that’s on my mind is that while this book was entertaining and addicting, I felt like that the

“Sandeke, I see your love, and raise you a secret handshake.”

Perfect book for an actual heatwave. I swear I have been burning up inside and out. Europe is boiling and so are Kaitlyn and Martin.

Heat is the second instalment in the Elements of Chemistry series and so far the best book in the series for me. The story starts right where we left off. Parker is trying to hide at the party after witnessing something that should have angered her, but

This series is addicting. Fast paced, witty, it's all consuming. I love the characters, the dialogue - Penny has sent me into full fan-girling mode. But that damn ending. Not pumped about some of this drama. Argh! I need to next book now!

I love a versatile author and with this series Penny Reid proved she’s exactly that. One of the things that remained the same is her smart and refreshing writing that for sure will entertain you from the very first word to the last. I think ‘Heat’ is the perfect title for this second book in the series. If the previous book was funny and the steam level was low to zero, this installment is scorching hot. Don’t get me wrong. This installment is funny as well, with some humorous dialogue

I will not be long on this, because I don't want to spoil the story for you.
This story is the second book of Katy and Martin’s story and this time family secrets and ghosts from the past are about to be revealed, and it will take a huge toll on their decisions and their relationship.
So, jump in and keep reading their story. You'll bot regret.

This ended in a way that I felt destitute, and completely depressed. I also felt the previous books' ending was like a walk in the park!

Elements of Chemistry continues to capture me and leave me begging for more. This series has Penny’s signature wit and intelligence, but also offers a level of heat and chemistry that is unexpected, but super enjoyable.

The first installment ended with a misunderstanding between Parker and Martin. So many times in books we are stuck in this land of misunderstandings and wasted time, I am so happy to report that Penny didn’t waste anytime.

Well, I have to admit that I liked this book better than the first. Parker and Martin have really evolved in their relationship and are working out all the kinks. They've become a lot of closer and have taken time to get to know each other better.


Of course, things can't stay good...there's has to be some kind of drama and there certainly the form of Martin's Dad. He really helps you understand Martin a lot better but that's the only good thing.

Although I liked this more than the first book, I still wasn't in love with it.

In this installment, Kaitlyn and Martin take their relationship to the next level. Meaning: sex sex sex. Yes, people. This book has them sleeping together like bunnies in the Spring.

I didn't find Kaitlyn as annoying as I did in Attractions. She said a lot of things that made me say "Yes, girl! Amen to that!!"

After the thrill of the chase in the first part, Kaitlyn and Martyn are holed up in their billionaires paradise island, eating grapes, working on chemistry assignments and getting gropey with each other under the stars. It is, as Kaitlyn observes with her usual insight, a little like relationship 101 for both of them, as they're both relationship novices and they both say and do some cringeworthy things.

Well...this was sure interesting. Heat is the aptly named second book in the Elements of Chemistry serial and this one definitely brought this book to a whole new level.

HEAT is the continuation of a 3 part series. In this second part, Martin & Kaitlyn are still on vacation with a few days left before they head back to school. Their feelings have intensified for each other and with any good romance, there's opposition and tension. Both of their families come into play in this installment and have caused Martin & Kaitlyn to identify with what they really want for their future.

Because this is a 3 parter this ends on a cliffhanger but luckily all 3 books are out s

A quick, short novella that was packed with drama! The continuing adventures of Kaitlyn and Martin, as they see if they can have a romance despite their messed up family patterns and potential conflicts of interest. This one had plenty of drama and sexy times. A fun light read.
