Sphere (Blackwood Security, #9.5)

When Emmy Black's personal assistant forces her to take a day off from saving the world and go to an amusement park, he promises it'll be a fun day out for her and the Blackwood girl squad. But it turns out the escaped monkeys are just the beginning, and before Emmy has even finished her first cocktail, she finds herself planning perhaps the most unusual rescue operation she's ever been involved in. Thank goodness she brought her duct tape. . .

Sphere is a standalone humorous thriller novella in the Blackwood Security series - no cliffhanger!
