The Land of Neverendings, by Kate Saunders

Three months after Emily's sister Holly has died, she is still processing the loss.  Her mother is always sad and Emily's friends are uncomfortable in her presence.  However, Emily is surprised to realize that the thing she feels the greatest sense of loss over is Bluey, Holly's teddy bear.  For while Bluey was definitely Holly's toy, Emily knows in her heart that if she could only confide to Bluey, everything would feel alright.  Unfortunately, they placed Bluey in the coffin when they buried Holly.

Amidst that longing for a lost toy and perhaps inspired by being cast in the lead for a school production of Alice, Emily stumbles across a portal to the world of Smockeroon, the land of the toys.  There she is presented with the entrancing idea that she could reconnect with Bluey (and perhaps even her own sister).  However, behind this opening between the "hardworld" and Smockeroon lies a sinister force -- a giant toad who wants to import all of the sadness of Emily's world into the world of toys, in an attempt to destroy the joy and happiness of that latter place.

In a very British way, this riff on CS Lewis and Lewis Carroll (with a unacknowledged debt to Pixar) explores the grieving of a child told through our relationship with toys and play.  The story is a bit chaotic and difficult to follow and the deeper themes will definitely fly over the heads of young readers.  Still, it's a clever book and it's nice to read something so sweet and innocent.  Entirely suitable for all ages.
