Tilly Chalmers loves her new job, but what is she to make of her dangerously attractive, but secretive, new boss Heller? Or the strange group of people that live with him? And could he really be a cold-blooded killer? After two hazardous first assignments and with a ruthless competitor on the scene, Tilly must decide if she has what it takes to survive the rough world of security work.Twenty-five year old Tilly Chalmers can't believe her luck when she lands a dream job at Heller's Security & Surveillance, despite a disastrous interview and no real experience or skills. An unsuccessful actor and almost down to her last dollar, Tilly hasn't accomplished much in life and is desperate to succeed in her new job. She finds herself attached to its many benefits, not the least of which is her dangerously attractive new boss, Heller. She soon discovers though that he is a man with secrets, leaving her with many unanswered questions. Why won't he tell her anything about himself and why is he using a false name? Does his brutal streak prove that he is a cold-blooded killer, as thought by some people?Moving into his combined office/residence, Tilly joins the strange group of people living there that Heller seems to have collected on his way: teenaged Goth, Niq; sensitive, scarred Daniel; colossal twins, Sid and Clive; and the shadowy Victor, who is never seen. Dwelling in close proximity to them all strengthens her growing bonds with Daniel and Niq, neither of who have ever had a positive female role model in their lives. It also tests her will power with Heller, particularly as he doesn't hide his growing personal interest in her. While she's mightily tempted, Tilly can't overlook his promiscuity or his increasingly possessive attitude.Not sure what to think when she realises that she's the only female in a business that employs a lot of terrifyingly large and loyal men, Tilly struggles to be accepted as a Heller's team member. Her first assignment, acting as companion to the bored young wife of a visiting rich businessman, doesn't go to plan and Tilly receives a violent introduction to the rougher side of security work. Her second assignment with a polygamous family pushes her professionalism and self-preservation skills to the limit. When her agent makes her an offer she shouldn't refuse, Tilly has to decide between her new life with Heller and his 'family' and something she thought she'd always wanted.
