The Work Wife by Allison B. Hanson

From boardroom to bedroom… Jamie Witmer recognizes a good thing when she sees it, whether it’s the elegant buildings she helps design, or her effortless working relationship with her partner, Weston Archer. But being the top team at their Boston firm doesn’t get Jamie and Wes invited to the couples-only bonding retreats and deluxe marital getaways. So Jamie has an idea—she and Wes will become married friends with (company) benefits…

Wes has been attracted to Jamie since she walked into his life five years ago, and her crazy plan has opened up all kinds of new possibilities. Fake marriage leads to even closer contact. Contact leads to temptation. And when they finally act on all that heat, the passion is more intense than even Wes could have imagined… They say if it ain’t broke, don’t fix it. But now that their friendship is irrevocably changed, it might be time for something even sweeter to begin…
