The griffin's riddle - Suzanne Selfors

Ten-year-olds Ben Silverstein and Pearl Petal have had quite
a busy summer in the typically quiet town of Buttonville. Ever since Dr. Woo
opened her doors, things have been more exciting than the senior center on
pudding day! Together, Ben and Pearl have encountered all sorts of magical
beasts -- from a sasquatch, to a lake monster, to a leprechaun, to a dragon, to
a unicorn.

In The Griffin's Riddle, when Ben and Pearl discover that Dr. Woo
and the sasquatch are both sick with Troll Tonsillitis, the two must travel to
the Imaginary World in search of the only cure -- a griffin's feather. But can
they convince the "King of Creatures" to surrender one? And at what cost?

Suzanne Selfors delivers a wild journey filled with mythical creatures
and zany adventures that are anything but imaginary.

in The Griffin's Riddle. These activities are designed for the home and
