The Opposite of Echo

David Shaw wakes in the hospital with a skull fracture and no memory of the previous week. But that is the least of his problems. His wife and teen stepdaughter are missing. As David works with police to recover memories of the crime and find his family, he has to regard everyone in his life as a possible suspect: his philandering law partner; his drug-dealing brother-in-law; the ex-con father of his step-daughter; the Russian mob. Any of them could be involved. One of them knows where David's family is. Will he be able to find them before it's too late?
