I find the books I love the most are the hardest to write about. This story was a breath of fresh air in a sea of young adult books that seem to retell the same stories over and over. The main characters being, essence, or soul inhabits a different person every day and has done so for their whole life. Then one day they fall in love with the girlfriend of one of the bodies they possess. What happens next was unexpected and wonderful to watch unfold. It was amazing to witness all the lives they encountered and to realize how easy it is to take for granted all the consistencies we have in life. Fascinating and engaging I had trouble putting this down and longed to return to it.
