Kate of Kratos — Robert Appleton

The final action-packed instalment in Robert Appleton's sci-fi survival trilogy.
 
Jason Remington has been abducted by a monstrous creature. Having barely survived the ocean crossing, Kate Borrowdale must track him through an alien forest and across its bizarre low-gravity roof.

Two men and a woman, also survivors from the Fair Monique's crash, arrive to help. But how are they still alive in such a deadly place? Kate senses they're hiding a secret and doesn't trust them. Things begin to look up when she finds a mountain cave for them all to live in. Procuring food proves tricky, however, as it means venturing back into the heart of the forest, where Kate finds herself being watched...by the real inhabitants...

The fight for supremacy in the wilds of Kratos takes on an epic new dimension in Book 3 of the (newly revised) trilogy, preceded by The Eleven Hour Fall and The Elemental Crossing.
