Pat Johnson & Barbara van Tuyl

I don’t think I can do better with this series than quote Susan Bourgeau, who provided the information and pictures for this section:

“ The Bonnie series is one of the series best loved by serious horse book readers in the US. The first book, The Sweet Running Filly, I'd classify as the best Young Adult horse mystery ever written (and I'm not given to hyperbole!). There's a superb Dick-Francis-like mystery, great characters, horse rescue, girl and horse bonding, and a touch of romance! “

All of the books were printed only in paperback, by Signet. The first two had dual authorship, Pat Johnson (who also wrote riding instruction manuals) and Barbara van Tuyl. The last three in the series were written by Barbara van Tuyl alone. The books were issued individually, and later as a slipcased set with the picture from Bonnie and the Haunted Farm on the sleeve. None of the books were published in the UK. They are available reasonably cheaply from the US.
