When is a cliffhanger too much of a cliffhanger

Cw: war, death, parent death

Hello! I was wondering if anyone could give feedback on how I want to end the first book of a trilogy I'm writing? Very short summary is that my MC is forced to fulfill a prophecy by beginning a war to unite two factions of vampires (ones who are normal and can't go in the sun and ones who have evolved from them who can go into the sun). Another key point is that some of the vampires ride ancient, giant, nightmarish small dragon sized bats called the Bhal.

Essentially what happena is my MC watches, beyond complete exhaustion, as the king of the daylighters is killed by the same man who killed her mother. She and her bhal try to save him, but the prince gets to him first. They land somewhat safely but the king is already dead. MC tries to heal him, but magic can only do so much and death is final.

Here's the exact last paragraph as it is now:

“Bring me Sebastian Crow’s head on a fucking pike,” Elias ordered, “He killed the King. Bring me his fucking head.” His voice shook with rage, and as the night burned around them, Astraya looked up at the stars and smoke above them and hoped her friends were still out in the village alive.

Thoughts/ideas/any feedback is super appreciated :)
