In The Garden of Echo (Paperback) (ISBN-13: 9788797604304)

Echo and Ender have existed nearly as long as the earth itself. They're hungry, in love, and indestructible.

For centuries they've wandered across continents feeding from their favorite food source - humans. But the mess they've left in their wake starts their prey on the path of discovering that they are not what they seem.

After being forced to curb their feeding and go into hiding, a tragic incident leads Echo and Ender to learn about what they are, and the power they are truly capable of.
