The war between the Kingdom of Night and the Kingdom of Rivers tore the mortal realm apart. Now it is an increasingly dangerous place, falling into eternal night where ravenous demons roam and every day is a fight for survival... The Immortality Trials offer a second chance in this brutal world and are open to any mortal willing to risk the journey to the immortal realm. The prize for completing them is eternal life...

However, first they must survive.

An'y ng knows the prize can heal her dying mother and that she'll need all the help she can get if she's to complete them.

But when a rival contestant, both powerful and handsome, promises protection and a chance of survival for both An'y ng and her mother, she will need to find out quickly whether she can truly trust the stranger she's falling for or if he's the most dangerous player of all ... for herself and for all the realms.
