Heller's Punishment — J.D. Nixon

Book 4 in the Heller series. In her latest adventure, rookie security officer Tilly Chalmers has three new assignments to cope with - chaperoning a devious addict to a rehabilitation clinic; live-in security for a strange and isolated religious cult; and protecting a national TV host in a damaging court case. On top of all of this, she must also somehow manage her growing feelings for her boss, Heller, and decide on what to do about her love-rat ex-boyfriend's demands to rekindle their relationship.
