Splinter (Book Three of the Sentinel Trilogy)

The critically acclaimed Sentinel Trilogy comes to a thrilling conclusion in this final instalment of the dark fantasy series. The world is falling apart around Nicholas Hallow. Amid rumours that the Dark Prophets have returned, a deathly gloom pollutes England, unleashing a savage hoard of nightmare creatures. Fighting the tide of evil, Nicholas returns home to Cambridge, where an old ally helps him seek out the mysterious Skurkwife, who could help Nicholas stop Malika and the Prophets for good. Meanwhile, Sam Wilkins unites the Sentinels against the forces of darkness, but with Jessica's sanity slipping, and Isabel suspicious of her shadowy past, it's a battle that could cost the Sentinels everything.
