They say that cats don’t like change. But Luna, an imaginative tabby, understands that sometimes it’s necessary. When her owner, Annika, moved back to her small New England hometown six months ago along with her sixteen-year-old twins, Luna knew it was for the best. Ever since Annika’s husband, Peter, died, the family has been floundering. Luna, too, is guilt-ridden, sure she could have done more to save her favorite person. Luna also knows something the others don’t know. Peter’s spirit is still with them, and Luna believes there is something he needs her help to do. Luna — unwavering in her affection — may be her family’s best hope of learning how to forgive and to heal.
