Kate SeRine, author of the Transplanted Tales series is writing a novella called Grimm Consequences which is a sequel to Red. Expected publication date is 14 February 2014. Book 4, also due in 2014, will feature Gideon (yay).
SeRine’s latest novel though Along Came a Spider will be out 1 August but I have an early review for you which will be out 25 July. FYI it rocks!
