It's in His Kiss — Deborah Shelley

When architect Patrick Godwin asked to see the man in charge of J.S. Construction, he wasn't expecting a woman. Jacqueline Santiago had a face like an angel, and an attitude that could freeze the desert sun. Clearly, she wasn't amused by his mistake. Patrick's instinct was to hop the next plane back to the east coast. But if he wanted a shot at his industry's most prestigious award, he was stuck for the next six months here in blazing hot Phoenix, with the Ice Queen herself.
Having just been dumped by her two-timing fiance, ambitious Jacki was wary when it came to men, all men. Especially the architect, who plans on building a crazy house for an even crazier client. Jacki is hardly in the mood for such nonsense, let alone romance. But Patrick is handsome, and she soon finds herself wondering if she's been too hasty to swear off men, and marriage.
