Sunny’s a spy who works undercover as a cop. It’s complicated. Pamela’s a dancer on Broadway. She’s not the star, and despite having a certain something, she’ll never be the biggest draw, because she can’t sing. But she’s arresting. Sunny can’t say why she shows up behind a theater on Broadway after a (lousy) show that night, but she leaves with Pamela in her car.

Instead of a one-night stand, Pamela and Sunny find they want more, that being together is both exhilarating and a balm to the soul. But they have secrets. Pamela doesn’t understand the implications of her secrets, and that spells trouble. Sunny knows the ramifications of her own shadowy past and shady present. These don’t make for a bright future, interpersonally, despite having a supportive work partner, Vash. But the thought surfaces, for both women, briefly–maybe this could work?

Then Pamela disappears. Sunny must use all her skills and all her connections, legitimate and under-the-radar, to find her lover. In the process, Sunny and Vash stumble onto a tangled conspiracy that could spell doom for Sunny and Pamela both.

The plot is fairly straightforward, though the mechanics of the organizations are a bit nebulous. It would be a good deal of fun to read a book just on Sunny’s training. But Adieu, Warm Sunshine is an entertaining read. It’s a little choppy and starts some threads that get dropped, narratively, although they’re tied up later. Writer design choices that don’t work as well as they could. But overall it’s a fun read. Case’s metier is in her sex scenes, where she exhibits a flair for choosing just the right detail to characterize the budding relationship between her protagonists. She works well on a smaller stage here. Though the overall plot can be explained in a linear paragraph, the book’s most successful parts are the interactions between Sunny and Vash, Sunny and Pamela, and Pamela and her roommate.
