Walking the perfect square

"August 6th, 1998; Moe Prager, a former cop, waits to call his daughter for her 18th birthday. In the midst of an ugly family meltdown, Prager is desperate to find a way to make sense of what has caused his once-happy family to implode. As he waits, however, it is Prager who receives a call that might not only solve a case that has haunted him and his wife for twenty years, but might also supply the glue to patch his family back together."--Jacket.
