World of Trouble by Ben H. Winters
The final book in a completely plausible pre-apocalyptic trilogy, World of Trouble finds former detective Hank Palace and his dog racing against time to find his younger sister Nico, encountering a cast of quirky characters. The asteroid Maya will probably hit Earth soon, but Hank keeps following leads from New England to a deserted police station in Ohio on his bike, and finds both hope and one last case to solve after he arrives. Hank is an appealing protagonist, and this book is just as compulsively readable as The Last Policeman (here’s my review of the first book) and Countdown City. World of Trouble will be available in mid-July.
