Ruthless by Venus Reising

After a sting operation goes horribly wrong, police officer Jackeline Raelston (Jacks) swears off the force and turns to private investigating. Riddled with guilt over the death of her partner, Jacks is determined to keep her heart and herself safe from danger. But that's before she's hired to find missing Southampton heiress, Cassandra 'Cassie' Wainwright. The search for Cassandra pulls Jacks into a world of intrigue and espionage where things aren't necessarily as they seem -- including the sexy and flirtatious heiress. The more time the two women spend together, the more Jacks becomes entangled both personally and professionally. But which is more at stake? Jacks's heart or her life? And is she willing to gamble on both...' --Publisher's description.
