Maggie Lee has had a lot of jobs, but her current employment may be the worst of the bunch. It's a real grind.

Recruited to work as a barista, Maggie contends with demanding customers, quirky co-workers and an overbearing teenage boss all while trying to surreptitiously gather the intel Ms. Whitehat needs.

She inadvertently overhears another plot (that's what happens when you're eavesdropping) and this one endangers someone she loves.

Can Maggie master latte heart art, help Ms. Whitehat, and protect her loved one; or will her undercover job end up with someone being six feet under?
