Welcome to the first book of the Chemistry series. I hope you enjoy this book and the others that follow it. Bad boy Calum Hood who intimidates everyone with his leather jacket, tattoos and the black sunglasses that are always covering his eyes and has a reputation for hooking up with girls and leaving them but once he sees her wearing his signature leather jacket that he left at her house after an eventful night he has the proudest smile on his face because "that's my girl and she's wearing my jacket". ** Calum and Emily are strangers until one conversation about an unusual hangover cure lights the spark of a truly bumpy story. ** THIS BOOK REALLY NEEDS TO BE CLEANED.
