I Spy is the second "Partners in Crime" book, the first being Dangerous Curves. "Partners in Crime" is a corporate security firm made up of former FBI agents and partners Aimee, Daphne, and Raine. Dangerous Curves was Raine's story; I Spy is Aimee's.
I Spy begins when Aimee is hired to uncover industrial espionage for McConnell Aerospace. She zeroes in on the most likely culprit, only to discover that he, in turn is focusing on her as a likely culprit for selling McConnell's secrets, not to another company, but to another country.
CIA agent Race Gardner and Aimee join forces to stop the spy, but only after Aimee makes it clear that she doesn't work for free.
Aimee and Race fall in love, but as things get more complicated, Aimee's avowed love of money makes Race's superiors believe she's sided with the villain. Both Race and Aimee, and their trust in each other, are put to the test in the page-turning, can't-put-it-down climax.
The suspense. The suspense in I Spy was truly gripping. I knew (thank goodness for that happy ending guarantee!) Aimee and Race would both make it out alive, and that they'd end up together, but just how they'd manage it was not at all certain.
The villain. The villain was particularly well-done, I thought. He was sympathetic and understandable... and completely ruthless.
The heroine's emotional arc. Aimee was her own worst enemy. Her stated intentions to work only for money, as opposed to dedication or duty, caused everyone but those closest to her to believe the worst, and caused even them to pause a little. Her fledgling relationship with Race was put to an extreme test of trust that they both passed with flying colors, putting a lump in my throat & tears in my eyes even as the suspense made my heart pound. (yes, I was a bit of an emotional dishrag by the time this story was done!)
Something happens near the end that I'm not going to spoil, but it's shocking and may ruin the book for some readers. As a frequent romance reader, I fully expected it to be avoided somehow, but it wasn't. It made the book more realistic for me, but YMMV.
The nice little bonus:
As in Dangerous Curves, there's a young girl--two as a matter of fact: Josie and Giselle. A little minor theme running through these books, it seems, of young girls being smarter and more aware than people give them credit for.
I'd been looking forward to I Spy since reading Dangerous Curves. I wasn't disappointed. In fact, I Spy has made me expect even more from Daphne's story. I can't wait!
