The Strange Tale of Hector & Hannah Crowe by Nathaniel Hensley is the first book in what I believe will be a new series. I think Hannah and Hector have a lot of appeal and will make a great series for young adults. Brothers and sisters may fight but most will protect each other when the chips are down.
Hector and Hannah have grown up at Strange Manor, which happens to be haunted by the original owner. So they are both a bit more used to hauntings and things that go bump in the night than your average person. Strange things have been going on in the lives of the Crowe children, but since that is fairly ‘normal’, they aren’t given the focus they deserve. It does not mean that others are so blase–Hector’s best friend still doesn’t like going into the main house, for a whole host of reasons.
