«Molly and Corry» by Chris Hart

Molly is an eleven year old girl whose best friend is a fully functioning A.I. computer called Corry. In their second great adventure they're on a mission to rescue a lost pet and as she finds out more Molly becomes convinced a crime has been committed. She even thinks she knows who did it. Corry gains the ability to see and creates a whole new set of problems for Molly. Dad proves he's a hero, risking life and limb and somehow, so does Molly's brother Tom.
The duo become sleuths to investigate and bring the culprit to justice. They recruit a wannabe spy, a retired spy and a spy in the sky, to catch a creepy spy guy and liberate a couple of dozen hostages on the way, while trying to get an “A” in science with Lizzie and definitely not looking cool in pink. Corry discovers she’s not alone and like most families they have their own problems, but usually ours can be fixed without space flight. At school Riley's still a pain and it looks like Jazzy the class bully has been arrested, but looks can be deceiving.
Molly and Corry conquer the perils of space and dare a rescue in an adventure requiring detective skills, bravery, a brush with death and the help of a local dragon Lord (retired)… and of course, dad.
