Knights Unite (Paperback) (ISBN-13: 9789526547305)

Riva du Lac is determined to keep her promise to her dad - no detentions in her first term at Spiral Hall. With just three days left, it seems like smooth sailing. But her plans capsize during a sea cleanup when she discovers Shem, a mythical fish-boy. A surprise honour from the school's Spiral Knights forces Riva to choose between following the rules or saving her new friend. Meanwhile, during a nap in assembly, Riva's classmate Peter Blue has a vision of a garbage-spewing sea beast attacking the knights.

With floodwaters rising and time running out, Shem's secret from the past may be the only hope for Peter, Riva and their friends to save the knights - and themselves.

Knights Unite is the fourth stand-alone novel in the Peter Blue science fantasy thriller series
