Sam Samurai (Hardcover, Turtleback School & Library ed.)

They've conquered the summer reading list, Greek monsters, and Roman gladiators, but a poetry assignment? Stuck writing haikus for English class, Joe, Sam, and Fred take one little break from doing their homework and BAM! -- they land smack-dab in the middle of seventeenth-century Japan. But how will the boys search out The Book and find their way back home when they're busy dealing with grumpy samurai warriors with really big swords?
