What couple will the next Whisper book feature? (And when can we expect it? 😉)
The next book, A Treason of Truths, features Sabine and Lyre, the empress and her spymaster, and it's out in early October this year! It focuses on political intrigue and danger on the Cloud Vault, a politically-neutral floating fortress of scientists. There's secrets and plant critters and kissing!
(Sorry for the delay on the answer! Somehow GR didn't notify me of this question.)
