I was pleased and surprised to find that the pre-order page for the US audiobook edition of The Wolf’s Call is already up on audible.com several months before it usually appears: https://www.audible.com/pd/The-Wolfs-Call-Audiobook/1984890816
Also, with the publication of The Wolf’s Call due in July, some people have been asking about the best reading order for the Raven’s Shadow series. To date, the series consists of three full-length novels, three novellas and one short story. As the novellas contain some mild spoilers for the novels, I’d recommend reading in the following order:
Blood Song
Tower Lord
Queen of Fire
The Lord Collector
A Duel of Evils
The Lady of Crows
Many Are the Dead
However, here’s the reading order if you want to follow the strict chronology of the overall narrative:
A Duel of Evils
Many Are the Dead
Blood Song
The Lord Collector
The Lady of Crows
Tower Lord
Queen of Fire
