“Kelly…keeps the story moving at a quick pace, which should easily hold baseball-lovers’ attention.” —Publisher’s Weekly
“…should score with the series chapter-book gang, particularly kids who enjoy the blend of fiction and information that keeps the Magic Tree House thriving…A scattering of black-and-white pictures and appended “Dugout Notes” extend the fun.” —The Bulletin of the Center for Children’s Books
“…Any 6- 9 year old baseball fan would step to the plate and devour this book like a box of Crackerjacks! Kelly intersperses the perfect mix of sports action, crime-solving and facts…” —Examiner.com

“Combining the twists and turns that young readers expect in a good mystery with a story line that builds upon each ballpark’s quirks and nuances is no small task, but The Ballpark Mysteries series pulls it off.

More than that, his allegiance to the actual history associated with each team and its park consistently hits the mark.” -–Josh Pahigian, author The Ultimate Baseball Road Trip and 101 Baseball Places to See Before You Strike Out
“Young baseball fans will love the Ballpark Mysteries series. David Kelly keeps kids reading with action, mystery, and plenty of baseball.” –Tim Green, former top NFL defensive player for the Atlanta Falcons and author of the children’s books, Rivals and Baseball Great
