This book was great! Since this book is from Gabriel Merrick's POV instead of Becca's, I wasn't sure how much I would like it. However Gabriel's perspective was fantastic and definitely didn't disappoint! I mean, how can you not like a book that has a line like, 
 "A girl on the cheer squad had once asked Gabriel if having a twin was like looking in a mirror all the time. He'd asked her if being a cheerleader was like being an idiot all of the time - but really, it was a good question." 
 I didn't really like Gabriel that much in Storm, however, in Spark he has swept me off my feet haha. After reading this book, you really understand why Gabriel is the way he is, and how tough it has been for him to control his power. Gabriel is so vulnerable in this book, and I loved seeing that side of him. I absolutely adored the relationship between him and Layne. I felt that it developed very naturally, and it was the cutest thing ever! 
 Layne is the total opposite of Gabriel in almost every way, but that is exactly why they work together. The relationship and chemistry seemed so right between them that it's hard to believe it was only just beginning. When things heat up (pun definitely intended) between them, it goes from sweet to passionate and explosive. 
 Hunter played a bigger role than I thought he would, but I loved that too. It was hilarious to see this "bromance" form between him and Gabriel. I'm looking forward to reading from his perspective in the next book because I'm interested to learn more about his powers, and how he handles them. 
 Ms. Kemmerer impressed me yet again with her flawless writing. I really connected to the characters, and I was able to jump right back into the world that she had set up in the previous book. One thing that I like about this series is that while the supernatural element is present, the characters are still dealing with issues every teenager faces. Each character is very well described and has a certain depth that you can't wait to delve deeper into. Ms. Kemmerer also left me guessing as to who was really starting the fires, but it was an interesting twist, and I look forward to seeing how it plays out. 
 I'm definitely itching to see what Ms. Kemmerer has in store for us next! And let's just say, Gabriel Merrick can save me from a fire anytime haha ;)
