One Piece, Vol. 46 continues where the previous tankōbon left off and contains the next nine chapters (441–449) of the on-going manga series.
This tankōbon begins the Thriller Bark Arc. The Straw Hat Pirates continue their adventure across the seas. After being stuck in a fog not even the sun can penetrate, the crew meets Brook, a living skeleton who immediately agrees to join their crew. Unfortunately for the Straw Hats, Brook lost his shadow on the giant ship known as Thriller Bark and cannot accompany them outside the fog.
Determined to have Brook as part of the crew, they go to the Thriller Bark in order to get Brook's shadow back. Tony Tony Chopper, Usopp, and Nami serve as the first boarding party, and find that the ship is inhabited by zombies. When the rest of the Straw Hats follow, they discover that Brook is not the only one who has lost his shadow, and that much of the island-like ship's populace have had their shadows stolen by Gecko Moria.
This tankōbon is written and illustrated by Eiichirō Oda. For the most part it is written and constructed rather well. The Straw Hats continue their adventure out into the Florian Triangle where they come across a strange barrel which upon opening, sets off a flare. This soon turns into a nightmare when a ghost ship directs them to the haunted island of Thriller Bark, where ghosts, zombies and Warlord of the Sea Gecko Moria await them.
All in all, One Piece, Vol. 46 is a wonderful continuation to a series that seems really intriguing and I can't wait to read more.
