Promise of Shadows 

A healthy dose of action, a strong thread of humor and just a touch of romance (VOYA, starred review). A teen who is half-god, half-human must own her power whether she likes it or not in this snappy, snarky novel with a serving of smoldering romance that Kirkus Reviews calls a dark, slyly funny read.Zephyr Mourning has never been very good at being a Harpy. Shed rather watch reality TV than learn forty-seven ways to kill a man, and she pretty much sucks at wielding magic. Zephyr was ready for a future pretending to be a normal human instead of a half-god assassin. But all that changed when her sister was murderedand Zephyr used a forbidden dark power to save herself from the same fate. On the run from a punishment worse than death, an unexpected reunion with a childhood friend upends Zephyrs worldand not only because her old friend has grown surprisingly, extremely hot. It seems that Zephyr might just be the Nyx, a dark goddess that is prophesied to shift the power balance: for hundreds of years the half-gods have lived in fear, and Zephyr is supposed to change that. But how is she supposed to save everyone else when she can barely take care of herself?
