Shadow Days follows Shay as he moves to his uncle's (Bosque Mar's) mansion in Vale, leading up to that bear attack which begins the events of the Nightshade trilogy. It was great to read from Shay's POV and learn a bit about him before we meet him in Nightshade through the eyes of Calla. It was quick with Andrea Cremer's signature writing and lines such as, "Several hours of reading about Katniss Everdeen's problems made me decide my life was pretty damn good." However, it was pretty much filled with things we already knew and so much of the discoveries by Shay within the mansion weren't that big. Still, it was a nice read and gave me another reason to return to Cremer's world.
