Mr. Romanov's Garden in the Sky — Robert Newton

Living in the commission, Lexie is left to fend for herself. Her mother is mostly absent, out searching for something to help her forget the tragic death of Lexie's dad.
But then, after witnessing the aftermath of a shocking incident, Lexie finds solace in the most unlikely of places - in a troubled old man called the Creeper.
A chance, life-saving encounter on the commission's roof seeds a friendship between the two and when they enlist the help of Lexie's friend Davey, the three set off on an epic journey; one that will change their lives and the lives of those around them.
