The third wonderful story in the illustrated magical adventure series with a powerful environmental message from the bestselling author of the Unicorn Academy.

The Keepers are secretive little people who live in the middle of Whispering Wood, caring for nature and rewilding it when humans (or Ruffins as they call them) are careless with it.

Young Keepers Cora and Jax are looking forward to the Moonlight Party raft race to celebrate Grandmother Sky's birthday - with their friend Trix's help, they have built a special raft. But at the same time they are beginning to wonder if they'll ever become fully trained Keepers, despite all their rewilding efforts. Then, after an exciting expedition into Ruffin territory to build a bug hotel and salvage supermarket food waste, they come across a young otter stranded in the stream that runs through the Hidden Middle of Whispering Wood. Suddenly the raft has a much more important role than Cora ever imagined.

Combining animal rescue, nature conservation and adventure, this brilliant magical series is perfect for 6-8 year-old readers.
