The Rising Mist is the final book of the beloved Mist Trilogy. Readers of Behind the Mist and Mists of Darkness have been eagerly awaiting its release.

In Celestia, home of the Legion of the Unicorn, the power of love prevails over fear. Nick and Bethany, immortal humans, are unicorn riders. Along with other legion members, they and their unicorns, Lazari and Shema, rescue and protect animals in danger on Earth.

After many successful trips to Earth, Nick and Bethany must face a personal crisis. The evil unicorn, Hasbadana, has captured Nick's sisters. When they try to rescue the girls, they, too, are imprisoned in a swirling mist of darkness.

When Urijah, the Lord of Celestia, sacrifices himself to take their place, Nick is determined to find a way to free him. It will take the combined efforts of the Legion of the Unicorn and a partnership with the animals of the Underground Kingdom to execute the unconventional plan.

But will that be enough to succeed?
