This series by Callie Barkley is one of my daughter’s latest favorites. Suitable for ages 5-7, four friends create The Critter Club to help abandoned and lost animals. The 8 year-old girls share their love for animals. Each book focuses on one of the girls and their individual lives while connecting it to animals. In “Amy Meets Her Stepsister,” Amy’s dad remarries and she gets a new stepsister. They do not get along until Amy discovers that her new sister is afraid of dogs. Amy helps her overcome her fear and they start to form a healthier relationship.  The books have pictures on almost every page (about 130 pages per title). There are currently 12 books in the series.
