How much loss can one soul endure?

Blue Eyes can't stop being reborn. He tumbles from life to life, from one unthinkably strange universe to the next - the only constant being that, one way or another, everything that he learns to love is lost. But when Blue Eyes finally catches up to a mysterious figure he's seen recurring throughout his lives, he realizes he might just have a chance to escape his cursed immortality - or, at very least, exact revenge for it.
