Romance author Vicki Lewis Thompson, whose comic change-of-pace title A Nerd in Shining Armor was a recent "Reading with Ripa" bestseller, has signed with Jennifer Enderlin at St. Martin's in a six-figure deal for three new Nerd titles. Enderlin won an auction run by agent Maureen Walters at Curtis Brown for the books, which will be published initially in paper, with the third moving to hardcover. Thompson has previously been published by Harlequin and Dell.
