I picked this one up knowing more or less what the story was before reading it but found it a quick, cathartic read. At other times, I might have dismissed it as too depressing but it was a fascinating peek into a dark reality, and one that hints at rather than lays out the horror propelling the narrative. 
 Letting Jack, the son, take the role of narrator was inspired. Although there were problems with his narration (the language and tenor felt far more like an adult projecting into a 5-yo, than a realistic story told from a 5-yo viewpoint), this conceit paid off. It allowed the big story to take place for the most part off screen, allowing a shadow play from those events to create a secondary narrative. 
 I was pleased at how prosaic the second half of the book was, and how flawed and human the author allowed the formerly grieving family to be as they went through a second crisis of rediscovery. 
 I don't know if I'd ever want to read this again but I felt it was a rich and worthy journey. Once.
