The Call That Broke the Class by Wallis Camp

On a sweltering weekend in R City, Wendy Hale thinks she's just stopping by her retired mentor's villa to borrow a few rare books—until a half-dressed heir storms in, mistakes her for his mother's newest "selection," and turns the afternoon into humiliation. She escapes… only to run headlong into someone she never expected to see again: Steven Lane, the man tied to the past she's spent years burying. Soon, roses appear where they shouldn't, anonymous calls won't stop, and a powerful multinational's "coincidences" begin circling her life with surgical precision. Wendy wants peace, but the closer she gets to the truth, the more it feels like someone has already planned her next step.
