Bosun Bob is a beautifully evocative tale of a tenacious sea-faring dog and his adventures at sea. Bob sets sail at dawn, leaving the safety of his harbour for the open ocean. He meets a series of mysterious and sometimes frightening sea creatures before his ship is wrecked in a violent thunderstorm. Bob is rescued from an untimely end and meets an unlikely shipmate in the process.

It is based upon the many adventures Erin encountered whilst living aboard her yacht Rocket with her family and dog, Bob. The creatures and lands she discovered shaped the tale of Bob, with Erin wanting to share the sense of wonder and magic she found on board with adults and children alike.
