Neilly's mom is having Declan's dad's baby. Neilly's dad is marrying a man. Declan's mom was killed years before while driving him to soccer practice. Pretty, popular Neilly features in Declan's fantasies, but in reality, she hardly knows he exists until they are about to be step-siblings. Written with boy/girl voices in alternating chapters in "he said", "she said" style, the story has laugh-out-loud funny moments. Declan's edgy, yet vulnerable, teen male voice rings especially true. Two teens with baggage begin to trust and blossom in a situation not of their own choosing.
