The Dragon Hunters by James Russell

When Coco, the dog, is let outside to go play, the two boys see a dragon snap him up.  When they tell their mother, she says, "Oh, sure."  Then it's time for them to go to bed...

Sourcebooks/Jabberwocky and Net Galley allowed me to read this book for review (thank you).  It will be published April 1st.

Flynn and Paddy get up early the next morning, pack themselves a lunch and head out to find the dragon.  Their mother assumes they are going after the dog.  She has that half right.

You can access a live map and use an app to see the characters in action and hear various noises as you read the book.  I didn't have that but the book is fine as a standalone.

It's a cute story where the children fumble through their rescue attempt but they succeed.  The illustrations are lovely.  And Mom still doesn't believe in the dragon.  There will be more books in this series, though.  Maybe they'll convince her yet!
