Impetuous [EPUB ebook] 

Grade school teacher Carlie Mc Daniels trades in her frumpiness for the look of an exotic harem girl, at least for one costume party. So long, spinsterhood-and hello, tall, dark and handsome Tyler Ramsey….Even after the best night of their lives, Tyler hasn’t guessed the identity of his harem hottie…and Carlie plans on keeping him in the dark. After all, a gorgeous guy like Tyler would never fall for his smart-talking best friend. And Carlie’s not sure she wants to know what would happen if he ever unveiled the naked truth!
