Stealing Chaos by Sarah Leyton

Roman Blinov might have rescued her this time, but Anna “Sway” Tyler isn’t about to give him what he wants or confide in him the secrets she carries. She’s on a mission, and he’s in her way.
Roman doesn’t trust criminals, especially not ones who change their identity as quickly and effectively as Sway. As they say, there is no honor among thieves. Forced to work together on a mission from Interpol to capture Sway’s financier, the man who taught her everything she knows, Sway and Roman must decide if trusting each other is worth the risk.
In the mean time, they’ll have to protect a wild group of orphans, secure a famous necklace, remember to feed an unwieldy pet, and decide if the emotions building between them are based on more than just the adrenaline and unavoidable circumstances.
