Deep Mettle Vol. II - Tools of War

"Little spark . . . you are changed . . ."

Antissa has come under Ratheine attack; not from the walls, but from below - her ancient pipes.

The flooded Hub threatens collapse of the Deep under the fortress, while the scheming Sanhedrin council creeps ever closer to removing Rusper Symphin as Viceroy; the engineer whose protection of the refugees from Naemia amounts to treason.

Tool to a nation on the brink, a Naemian boy enters the desert. Armed with the Disc's arcane 'Sight', Florian Flint now takes his place on a secret task-force contingent led by the High Commander Plamen. Its urgent purpose - in nine days - to locate the hidden river system by which the Rath accessed the pipeworks: the key strategic advantage in Vorth's return to open war.

The Disc itself has other thoughts.


The Cycle Schyluscient is a prospective 5-part series of fantasy novels set in and around the isolated Inwold realms. The opening instalment of the series, Deep Mettle, will be released in 2 volumes; available from Amazon KDP in paperback, hardcover and e-book formats. Cover art for both volumes is by Nataša Ilinčić.
