Jason and the Wonder Horn

Susan Kemp is a high-school teacher in Kingston, Ontario.

Twelve-year-old Jason has moved from Toronto to a rundown old house near
Cobourg, Ontario. There doesn’t seem to be much to do, and there’s
no one to hang out with. Jason can’t even find hidden treasure in the
attic—all that’s there is a battered old bugle. Things change when
Jason meets Charlotte and her brother, Squid, and Charlotte’s
grandmother teaches Jason to play that very bugle, which she believes
once belonged to Jason’s great-uncle Joseph. But not only that, she
tells a wild story about the instrument—that Joseph claimed to be
transported to different eras by the bugle.

The three children improvise a band and one afternoon, on an ordinary
country path, they are transported by the music to a world of dark
forests and a medieval German castle. What magic has taken them there
and how will they get back? Both questions are answered in a way that
will enthrall not only children but adult readers as well.

As time-travel adventure stories go, this is a fine one. Its suspense,
action, fantasy elements, and likable characters will have readers
turning the pages. Recommended.
