The ninth and tenth volumes of Hiromu Arakawa’s Fullmetal Alchemist continue to be excellent. These contain an arc of consequences from volume 4 (the Lab 5 arc and associated developments), which are exciting, emotional, and surprising. And, to my joy, include much more in the way of characters acting collaboratively, which was a thing that annoyed me about the original anime. I only disliked one thing, where I felt that drama overrode logic in the timing of a revelation, but it was minor. Read them together, as volume nine ends on a cliffhanger, but definitely read them.
