Once you’ve read this book, the adventure continues with Are We Twins? Purdy Franklin Mysteries #2.
Persephone Franklin, an ordinary deaf girl, first turned into a deaf cat on the night of her tenth birthday. At first, she thought it was a dream, since she woke up the next morning as a girl. But her behavior began to change during the daytime as well, and her reactions became more catlike.
When she was upset, she would hiss and form her hands into claws. Her friend, Rowen Carter, who used a wheelchair, suspected Purdy might be a cat, but he didn’t voice it at the time.
One night, Purdy showed up as a cat at Rowen’s house with a note taped to her collar telling him she became a cat at night. He wouldn’t take her word for it until she proved it. When he asked her to play something on the keyboard, and she did, he finally believed her. He came up with a grand idea of having Purdy go out as a spy-cat at night.
As a cat, Purdy could enter places a human wouldn’t go, but as a deaf cat, she needed to get close enough to the bad guys to read their lips. By following clues, she helped Rowen solve the mystery of The Unkindness Club, where suspicious characters lurked in the dark and sent unkind notes to their neighbors.
Many close calls followed as Purdy adjusted to her new transformation. As a cat, she became a target for her twin sisters, who wanted to claim her as their own cat.
As a girl, she became a target for The Unkindness Club after bringing home a mother cat and six tiny kittens. Because she had too many cats, animal control picked her up one night.
Come along and discover the many twists and turns as a ten-year-old girl-turned-cat and her best friend in a wheelchair solve the mystery of The Unkindness Club.

He decides to call her Purdy, and she really is a cat, but only at night.
