Heller's Regret (Heller #6)

Book 6 in the Heller series. There’s not much ordinary about Tilly Chalmers’ life as a security officer. Her latest assignments – two jobs involving children; protection of a valuable jewellery collection; and security at an unusual conference – provide plenty of adventures for her. But it’s her private life, including her complex relationship with her beautiful boss, Heller, causing her greatest personal challenges yet.
