It starts as a simple job - but simple jobs, when you're dealing with the magical world, often end up anything but.

As a Retriever, Wren Valere specialises in finding things gone missing - and then bringing them back, no questions asked. Normally her job is stimulating, challenging and only a little bit dangerous. But every once in a while ..

Case in point: a cornerstone containing a spell is stolen and there's a magical complication. Wren's unique abilities aren't enough to lay this particular case to rest, so she turns to some friends: a demon, a mage who has lost his mind, and a few others, including Sergei, her business partner... and maybe a bit more?

Sometimes what a woman has to do to get the job done is enough to give even Wren nightmares...
