Fans of Sara Pennypacker and Katherine Applegate will

love this thrilling environmental fable—filled with laughter, music, and

adventure.

There’s no other place Tubs Marshfield would rather be than

singing a song in his perfect little swamp along the Louisiana bayou. His music

can make anyone feel happy.

But something terrible is happening within the

swamp that even Tubs’ songs can’t fix—and it’s making his neighbors feel sick!

No one knows what to do, least of all Tubs.

A mysterious prophecy may hold the

key…or send Tubs away from his friends forever.
