Heat by Penny Reid is the second book in her Elements of Chemistry series. It continues immediately from where book one, Attraction, left off and jumps right into the story. This is a series that must be read in order and this review contains spoilers for the first book. 
 Martin has confronted Kaitlyn about her indifference to him. She believes he is still just a temporary thing. Why else would he leave her alone at a party and let some girl shove her tongue down his throat? Well, he was trying to NOT be a possessive jerk just as Kaitlyn requested AND he didn't ask to get kissed and pushed the girl off immediately. Once Kaitlyn is finally found, in the laundry room, reading a book, and this is explained to her, she begins to see the truth of Martin's account of events and after an emotional outburst and some yelling from the two of them, things seem to be back on the mend between them. Yay! And that's just the first chapter or so... LOL 
 Kaitlyn is so wonderfully contained. everything is all logic and reason purposeful. Martin, on the other hand, barely contains himself. He feels and emotes and pushes in everything. Never mind that he is a self-described "shy" person, he pushes past his own limits of comfort and has put his long term goals in action. He means to see them through to the absolute end. 
 When those goals, however, put him and Kaitlyn at odds what will he choose. His love with Kaitlyn or the one thing he's been after for as long as he can remember? It's a conundrum that, unfortunately does not get answered within these pages but I'm sure will be in the next and final installment of Penny's masterpiece... Capture. 
 The plot twists that you don't see coming, the personalities that you WILL grow to love, and the baddies that you would be willing to murder if they weren't fictional creations of text and paper. I love Penny's writing style and I always feel like her books, more than most, deserve a quiet space and peaceful time to read in. I do however drag them with me wherever and whenever I get the chance because they're her books :-D
