Tobsha Learner, the author of three books, is best known for her collection of sexy short stories Quiver (1997), which is not to be confused with Nikki Gemmell’s Shiver (1997). Learner’s latest effort is also a compilation of sexually charged tales. Tremble, however, is more ambitious than her previous offering. Instead of assembling all her characters in one city (Sydney) and in a contemporary setting to perform naked gymnastics with one another, Learner scatters her new cast all over the globe and within various time frames. From somewhere off the Cape of Trafalgar in the early nineteenth century to a stuffy British museum in 1851, from the dustbowl of Oklahoma to a tiny Greek island, Learner’s lusty protagonists gasp and moan their way throughout the night.
