Not My Friend by Reba Bale

Gina Hamilton has exactly three priorities: keep her nonprofit funded, keep her clients housed, and keep Kimberly Hernandez far away from her.

The first two were going great until Kimberly walked into Gina’s office with a state auditor’s badge and a checklist that could shut down everything Gina’s built.
They were in love once, until three years ago when Gina accused Kimberly of cheating and destroyed the best relationship she’d ever had. Kimberly moved out, moved on, and now has a new job with the power to ruin Gina’s career.
Reviewing files and reports leads to late nights, close quarters, and painful reminders of why they fell so hard, so fast. Gina knows an apology can’t undo the damage she caused, but the more time they spend together, the harder it becomes to ignore the feelings still burning between them.

Kimberly isn’t interested in rekindling anything. She’s here to do her job, not risk her heart on a woman who already broke it once.

But when the audit uncovers a financial discrepancy that threatens the nonprofit and the families depending on it, Kimberly must decide whether she can trust Gina again or if some relationships are too damaged to survive a second chance.
