Gemma hasnt been able to feel any emotions until recently because of some unknown reason. Then a guy named alex shows up at her school who seems to know more than he lets on. 
 I must say the start of the book seemed quite cliched with the guy being an ass and the two leads assigned on a project together but it didnt put me off. Things get more nteresting when the secrets get revealed about who alex and his sister are and what they have to do with Gemma's mysterious life. 
 Gemma's character was quite awkard, pathetic and annoying at times but in a funny way which made her likable. Alex was hot but also a major ASSHOLE at times with his secretive and elusive demeanor which made me want to punch his lights out for not telling gemma everything. Laylen was my favourite character and the most interesting and i hope there is a love traingle with him in the fiture books. 
 All in all, it was a very enjoyable book and fast paced that kept me hooked to the page till the end and i managed to finish it within a couple of hours. Word of warning, there is a major cliff hanger at the end...
