I have started The Silver Gryphon, book #3 of The Mage Wars Trilogy by Mercedes Lackey.
Time
passes and those heroes who do not die in a blaze of glory retire
basking in it, leaving and training the next generation to take up the
reigns. So, two millennia hence, it will be with Kethry and Tarma
training Keth's granddaughter Kerowyn; so did Talia raise Elspeth from
royal Brat to Herald-Mage. Mercedes Lackey has always been excellent at
these time shifts, and now, twelves years after the Eclipse Ceremony
that brought Haighlei and k'Leshya together, Tadrith Skandrakae and
Silverblade – children of Skandranon & Zhaneel, Amberdrake &
Winterhart – seek to escape their parent's very long shadows. After all, what can possibly go wrong in an isolated outpost weeks away from home? Certainly no magical disasters or nameless terrors possibly unleashed or formed by the Cataclysm in the unexplored jungles of the south. Oh no.
