Lincoln Rhyme, Deaver's popular paraplegic detective, returns (after The Vanished Man) in a robust thriller that demonstrates Deaver's unflagging ability to entertain. But even great entertainers have high and lows, and this novel, while steadily absorbing, doesn't match the author's best. Geneva Settle, who's 16 and black, is attacked in a Manhattan library while researching an ancestor, a former slave who harbored a serious secret (not revealed until book's end). Amelia Sachs, Rhyme's lover/assistant, and then Rhyme are pulled into the case, which quickly turns bloody.
