Her Book of Pleasure (Harlequin Blaze, #302)

Japanese art expert Megan Michiko O'Malley has many talents, but seduction isn't one of them. Yet after meeting a sexy stranger at a wedding, not only does she have an impromptu romp in the upstairs bedroom, but it's the most sensual sex she's ever had. Meg might have slipped out of Rick Sokol's bed without leaving her real name or phone number, but that won't stop him from finding her. He isn't one of the best private investigators for nothing. Besides, he needs her expertise.

He's just discovered an erotic Japanese pillow book and is hoping Meg will be his study partner! Rated '4/5 - Explicit open door' for steam/spice/heat level.
