Phoenix Knights: Journey to Safehold - Phoenix Knights, #1

The most epic Arthurian Celtic pagan high fantasy novel series that centers on the themes of reincarnation and found family, and features POC and LGBT characters, an elemental magic system, and a whole bunch of saving the world shenanigans. Betrayed. Reborn. Hunted. If you were given a second chance, would you take it? The immortal Nevinon has hungered for the sweet mercy of death for more than a century.
He has lost everything: his home reduced to ruins, his family sunken in forgotten graves, and his closest friend, King Alanor Kova, dead in his arms. When a ritual designed to end his suffering goes wrong, Nevinon accidentally manages the impossible-reincarnating King Alanor and his knights. Now, Nevinon and his friends must abandon their homeland to escape the witch hunters who have conquered their kingdom.
They must find Safehold, a mythical sanctuary for those with magic, before the hunters find them first. However, the hunters have gained a new ally. Something else has followed the knights through the Veil between worlds. Something ancient, evil, and determined to devour the source of all magic itself.  Through it all, questions linger in Nevinon's mind. Because the blessings of magic never come free.
His family has been returned to him, but for how long?  And in exchange, what will he be forced to pay?
