In Flesh and Blood, Trick reveals that Bo was named after her.
Isabeau died in The Great War when The Blood King's signature was forged on a dispatch ordering assassins to kill her after she went in secret to meet privately with Horvis, the leader of the Dark Fae army, in an attempt to settle the differences between the two clans and broker a peace truce. (Flesh and Blood)
The Blood King, in frustration, had suggested using his blood to force a treaty between the Light and Dark; but Isabeau knew that using his Blood Sage powers to end the war would create unintended consequences.
Although Bo was named after Isabeau, her name, however, is spelled with a "Y" (Ysabeau).
