The Legacy of the Heroes of Olympus: The Son of Neptune

Percy woke up in the Wolf house with almost no memory of his past besides his name and the name Annabeth and the sword in his hand, where he met the she-wolf Lupa and the Cloud ninja kunoichi Yugito Nii. Now they made their way to the Roman camp and met Hazel Levesque and Frank Zhang and must help them save the camp from the bane of Neptune and Pluto and their armies.
