The Shadowhand Covenant comes out October 22nd and is the sequel to The Vengekeep Prophecies.
Partial quote / paraphrased Kirkus Review with link:
Through mayhem and twists, Jaxter's cheeky attitude keeps this second volume flowing.
Jaxter is the main character. The lad on the cover. Second volume as this is the sequel. I mentioned that above.
It opens with classic Grimjinx shenaningans: a craftily narrated sham funeral, arranged to empty the mourners' houses for easy thieving. Jaxter returns from his apprenticeship to join the mischief. Soon after not-actually-dead Nanni reappears for supper, Jaxter, Ma and Da are summoned by the Shadowhands, "elite thieves-for-hire" who operate in total anonymity. High-spirited fun, with complexity and surprises. (Fantasy 8-12)
