Spellslinger
MAGIC, INTRIGUE, AND A MURDEROUS TALKING SQUIRREL CAT
HOW FAR WOULD YOU GO TO WIN BACK YOUR MAGIC?
Kellen is moments away from facing his first mage’s duel and the start of four trials that will make him a spellcaster. There’s just one problem: his magic is gone . . .
“A tremendously fun read full of wit and action.”– James Islington
“An intriguing system of magic, wry humor, and a twisting plot make for an entertaining series debut.”– Kirkus
The Greatcoats
THE ACCLAIMED SWASHBUCKLING FANTASY SERIES
THE GREATCOATS: LEGENDARY HEROES, ARBITERS OF JUSTICE, OR NOTORIOUS TRAITORS?
The King is dead, the Greatcoats have been disbanded and Falcio Val Mond and fellow magistrates Kest and Brasti have been reduced to working as bodyguards for a nobleman who refuses to pay them. Things could be worse – their employer could be lying dead on the floor while the three of them are forced to watch as the killer plants evidence framing them for the murder. Oh wait, that’s exactly what’s happening.
“Fantastic from the first sentence to the last.” – John Gwynne
“An energetic, fun adventure that puts the ‘musk’ back in ‘musketeer.’ Guaranteed to increase household swashbuckling by 100%!“ – Kirkus
