Jeremy Harper and Isabella McNamara have a deal: She will be his mistress for six months, and he will take care of her. For Jeremy, who doesn't believe in happy marriages, it's a chance to exorcise Isabella, an obsession he's had for years. For Isabella, it's the toehold she's needed to re-enter the jet-setting society she was dumped from when her father lost his fortune. And, more than that, she's betting that when she's finished being the Six-Month Mistress (3), she will be a forever wife. Katherine Garbera's characters are likable enough, but the plot pivots on a shaky foundation.
