The conclusion of the Amazon and Audible bestselling Halfhero series

When The Deterrent comes out of hiding and kidnaps the titans, it triggers the biggest manhunt in history.
On one side, the military might of the United States and Air Commodore Fiona Bardock, Britain’s most talented investigator.
On the other, three halfheroes, one human, and a puddle of slime.
Daniel Harbin hopes to get through this alive and track down the children he never knew existed.
What no one realises is they’re about to confront the greatest danger of all.

Reviews for the Halfhero series:

Love the style and originality of everything Mr Sainsbury writes
gripping and unputdownable
Ian W Sainsbury could well be the 21st century equivalent of Arthur C Clarke
A rollercoaster that never heads where you think it’s going
If you like the works of Charley Stross, Neil Gaiman, people of that ilk, give this, and its sequel a go
