Young San Diego authors publish conservation-themed kid’s book

Leave a comment

The Carmel Valley (San Diego) father-sons writing team has done it again. Henry, Josh (13) and Harrison Herz (11) just published their second book, Twignibble. Twignibble is a 1000-word easy reader for kids in 2nd-4th grade that’s Frog & Toad meets MacGuyver. It will appeal to animal-loving kids and to parents who support conservation (and who want to encourage their kids to be empathetic and resourceful).


Twignibble the sloth learns that his animal friends are facing threats to their habitats, and races to help them. The mechanically-inclined Twignibble, knowing he could never walk to his friends in time, builds a solar-powered helicopter, flies all over the world, and engineers devices he hopes will help each of his animal friends.

The wonderful independent bookstore Mysterious Galaxy Books will be hosting a book release party for Twignibble from 2-4 pm on Sunday, August 4. They are located at 7051 Clairemont Mesa Blvd., Suite #302, San Diego, CA 92111 ~ 858-268-4747. The Herz men will be there signing copies of Twignibble. Also in attendance will be James Morris, local teen author of Skybound and Water Tower.

Henry Herz is a member of the Society of Children’s Book Writers & Illustrators, and writes for the San Diego Children’s Books Examiner. He and his young co-authors’ first book was the fantasy early chapter book Nimpentoad. It has earned 86 Amazon 5-star ratings so far. Nimpentoad has reached as high as #8 in Amazon Best Sellers large print sci-fi & fantasy, and #1 in Kindle Best Sellers large print sci-fi & fantasy. The father-sons team has been featured in Young Entrepreneur, Wired GeekDad, CNN iReport, Fictional Frontiers, the Warner Brothers’ website for The Hobbit movie, and TheOneRing.net. The trio is looking forward to attending this year’s San Diego Comic-Con.

If you live in San Diego, we hope you’ll come out to meet the authors and enjoy the great selection of books offered by Mysterious Galaxy Books.
