Collateral Damage: A Disappearing Inc. thriller

Katy King with her sister Marsha runs a "Dissapearing inc.", agency you contact when you want somebody "lost or found".
Katy is a field operative, while Marsha is computer wizard running things from their office, chewing her bubblegum.
When they decide to help Jason Cooper find his missing sister who disappeardx without a trace, little they know in what crazy action packed adventures will they find themselves in.

Collateral damage is a action thriller (more action then thriller) full of action with a sprinkle of humor in right places. All characters are awesome (especially Marsha), their interactions interesting, funny and very early on you start to care about them. Book was very interesting to read, it wants you to read it fast with its twists, and I felt like I was reading an action movie.
