The Twin Sheikhs by Kate Goldman

Blake is chosen to design a house for the impossibly handsome sheikh and crown prince of Al Huddah, Bassem Sedarous. Although the young architect is excited to land a big assignment, she is confused by his behavior. When they meet to discuss the project their conversations are awkward and he is very cold to her, but outside of work he is very friendly and seems to be a different person. After Blake learns Bassem’s secret and supports him in a difficult situation their relationship takes a new twist and they begin to fall in love with each other. When everything seems to be against them as a couple, Bassem makes a decision that nobody expected – not even Blake.
