Three bear cubs of different species are united for the first time as they begin their long journey in search of destiny, hope, and what it truly means to be a bear in the wild.

The four bears finally arrive at the legendary Last Great Wilderness, thinking it is the end of their long journey, but they discover that their true mission has really just begun.

Moons have passed since six cats set out on a journey to save their Clans. Meanwhile, back in the forest, Firestar and Leafpaw watch ThunderClan's world crumbling around them. Will the questing cats make it back in time, or will they be too late?" As they journey home to warn their clans of the coming destruction, the six cats, guided by StarClan's prophecy, meet an unfamilar tribe of cats with their own set of beliefs--and their own mysterious prophecy....

At the edge of the Endless Ice, the four bears Ujurak, Toklo, Lusa, and Kallik reach Star Island, where a large group of bears is in trouble but believes Lusa is destined to help bring back the favor of the spirits.

ThunderClan's darkest hour is upon them and Fireheart, the warrior cat, must protect his clan from a threat unlike any the forest has ever seen, as the time comes for prophecies to unfold and heroes to rise.

"The four bears have reached the mountains where Toklo spent his cubhood--but they soon discover that the home Toklo has returned to is nothing like the one he remembered"--

When the bears return to Great Bear Lake for the longest day gathering, they find their reunion more challenging than they expected.
