Left Turn at Paradise — Thomas Shawver

The author of The Dirty Book Murder returns to the surprisingly lethal world of rare books with a second enthralling novel featuring a most unlikely hero -- antiquarian bookseller Michael Bevan.
 
Michael Bevan is barely scraping by with his used bookstore and rare book collection when he discovers a timeworn journal that may change everything. Dating back to 1768, the tattered diary appears to be a chronicle kept during the first of legendary seafarer Captain James Cook's three epic voyages through the Pacific islands. If it's as valuable as Mike thinks it is, its sale may just bring enough to keep his faltering used bookstore afloat for another year.
 
Then he meets a pair of London dealers with startling news: Adrian Hart and Penelope Wilkes claim to possess the journal of Cook's second voyage. Is it possible a third diary exists? One which might detail Cook's explosive final voyage -- and his death at the hands of native Hawaiians? Together, all three would be the holy grail of Pacific exploration. But before Mike can act, the two journals are stolen.
 
Chasing them down will sweep Michael, Adrian, and Penelope across the globe -- past a dead body or two -- and into a very sinister slice of paradise. High in the Southern Alps of New Zealand, in a remote and secretive Maori compound, a secret rests in the hands in of a man daring enough to rewrite history . . . and desperate enough to kill.
