Immortal Longing by Chloe Gong
Every year, thousands in the kingdom of Talin will flock to its capital twin cities, San-Er, where the palace hosts a set of games. For those confident enough in their ability to jump between bodies, competitors across San-Er fight to the death to win unimaginable riches.
Princess Calla Tuoleimi lurks in hiding. Five years ago, a massacre killed her parents and left the palace of Er empty…and she was the one who did it. Before King Kasa’s forces in San can catch her, she plans to finish the job and bring down the monarchy. Her reclusive uncle always greets the victor of the games, so if she wins, she gets her opportunity at last to kill him.
