The Chronicle Gate vol 1 - Ethereal #745650

What if you ended up on a planet. . .and had no idea how you got there?
The Elouse are creatures who live on the planet Ethereal. When they find a human child lost and alone, they take him in and care for him. Sinya, the human child, struggles to remember anything about how he got to Ethereal. As Jasper, the Elousen father, searches for answers, Sinya’s new mother Ellen and her daughters Taylinn and Avigale help him adjust to life on their planet.
Taylinn's dad is going on a secret mission aboard a space ship. Taylinn overhears that the mission is really “to save his family from him?” Could he mean Sinya? Sinya starts seeing Mer-Dragons, a made-up tale told to him by Avigale and Taylinn but this Mer-Dragon talks to a being known as “Malic,” one that means danger for Jasper and the family. But no one will believe Sinya when he tried to warn them of the danger. When Taylinn finally sees the truth of the danger for herself, she tries to alert her friends, but just like Sinya, no one will believe her, including her mother. Now in order for Sinya to get back home, these unlikely pair must team up to save Jasper, and his family from the coming danger of Mer-Dragons!
