Malachi and the Dragon — Abigail Hilton

Eve and Athena have enjoyed a good ratty life with Malachi in the blackberry bushes behind the farm. They've gone on adventures, made friends, and created a family. Eve can feel herself slowing down, but she's not worried. Eve has done everything she ever wanted. Except…Malachi still doesn't have his wings. Then one day the coyote returns, seeking to pay the debt he owes to the rats and the snake. He has found the dragon who can grant Malachi's wings. The way will be dangerous, but Eve thinks she has the strength for one last adventure. This is the 6th and final volume in the Eve and Malachi series.
