The discovery of a dead body is nothing new for Detective Simon Grave, but when the body and the murderer are both invisible, well, that's another matter entirely, even in the futuristic town of Crab Cove. The question is whether he and his human and android team are up for the challenge, which also remains to be seen. Making his job even more difficult is the sudden retirement of Captain Henry Morgan, who taps Grave as acting chief. And working two jobs becomes even more complicated when other bodies show up-or actually don't show up, sort of. One thing is certain, though: it all begins (and perhaps ends) with The School of Casual Invisibility, a school that has trained scores of people to become invisible at will. Publishers Weekly describes Boswell's PenCraft Award-winning series as a "genre-defying" adventure. As with all Simon Grave mysteries, simdroids (androids who resemble famous people) play a critical role in solving the crime. Expect humorous takes on the advance of technology, the effects of global warming, and nothing less than the meaning of life, death, love-and invisibility. Get ready for a fun read. The year is 2054, and not seeing is believing.
