01 High Risk - Vivien Arend - 3.5 stars

Rebecca James is an adrenaline junky.  While out on a rescue her partner dies and she loses her memory of the event.  Marcus Landers runs his Lifeline team.  When Becki shows up he tries to reignite their passion from their affair seven years previous.

The two of them push each other to be better.  In the bedroom, Becki lets Marcus be alpha male but in the outside world, she doesn't take any crap from him.

The downside to this book, Marcus' backstory of how he lost his arm was an afterthought.  The reader gets bits and pieces of her history.  His story isn't woven in until the very last chapter. If felt like the author realized she forgot his backstory and tacked it on the end.
