The Sunset Lullaby

The Sunset Lullaby is a song played by Mikoa at the beginning of Book 1. It reappears several times in the series.

"Come down, sweet sky, and rise my moon,""for day’s heart breaks, and sleeping soon.""What wonders all I rush to see,""please those I leave, remember me.""Though from this light I glide away,""tomorrow comes, another day.""And from above I watch and say,""my love, my lost, forever stay.""Your dreams are safe and quiet now,""no harm to you I will allow.""Look high, speak well, do never fear,""in peace I wait, I’m always here.""Come down, sweet sky, and rise my moon,""for day’s heart breaks, and sleeping soon.""What wonders all I rush to see,""please those I leave, remember me."

Interpretation
Ostensibly, the song is about death, sung by the dying, though it is meant to comfort loved ones left behind. ("Your dreams are safe and quiet now, no harm to you I will allow...") It implies a beautiful afterlife. ("What wonders all I rush to see...")

Mikoa thinks of the song when she thinks of her lost mother, Callandra.

Foreshadowing (Spoilers!)
The song bookends the entire Grim Dream series and foreshadows Mikoa's departure to the stars at the end of Book 9. ("And from above I watch and say, my love, my lost, forever stay...")

It is also referenced when Nazagorn steps through the Portal of Sunset at the end of Book 3, and when Mikoa tries to commit suicide by blowing up Sinthrall's volcano at the end of Book 1. Mikoa sobs, "please those I leave, remember me!"

The song also foreshadows Althuzah's defeat. ("Your dreams are safe and quiet now...")
