Twelve year old Logan already feels like the odd one out, the awkward one of the family, and when everyone abandons her to the mercy of a skeleton-thin housekeeper and a hate-filled parrot, she decides to strike back -- by becoming impossible.

But then she meets Tiff -- a truly impossible cat, who can talk, cook, and play the piano.

Tiff helps Logan to change her life, not by behaving impossibly, but by doing what everyone else is convinced is impossible.

A warm, funny and emotional novel which introduces Tiff - a truly amazing and endearing cat who is able to help families to resolve their problems.
