I like Spark. 
 ***** 
 Two things first: 
 If I think of action scenes, Storm is way better than Spark. 
 But if I think of romantic scenes, Spark is way better than Storm. 
 I was excited to this sequel because of Gabriel. See, I really liked him in Storm. A glimpse here and there of his wicked character is enough for me to root for him. But... Spark came across as a contemporary romance more than a paranormal one. I'd say only 10% of the book showcased the paranormal side of the Merrick brothers. :( 
 I missed Gabriel from the first book. Yes, he was still a smartmouth here, snarky and defiant. But Gabriel was always angry, hurtful, and secretive. I was looking forward to reading more about his relationship with his twin Nick, but (surprise!) they didn't talk half the time! All because of a girl. Ugh. 2/3 of the book was about Gabriel's drama. 
 Layne was okay. Not as strong as Becca but not a pushover, either. Except with her father. and what kind of best friend she has in Kara? It was obvious she's as flaky as she looks. And Hunter... I knew there was something going on. Hunter following Gabriel around like he has this girly crush on him, showing up every freaking time Gabriel needs a friend... only to know he has a hidden agenda. *snickers* I knew it! Becca's right. Hunter misleads everyone around him. but I liked how he pointed a gun to the firemen holding Gabriel. so bad*ss. 
 The mystery behind the series of fires was not handled well. Gabriel didn't even tried to investigate who the arsonist really is because yeah, he's wallowing in self-blame. 
 I can wait for the next installment, Spirit, which features Hunter (boo!). As for now, I will settle with Spark and the other novellas of the Elementals series.
