King in Limbo Omnibus 2 (Vol. 3-4) Vol. 2 (Kodansha, 2024)

In panicked whispers, the word spreads: The Sleep has returned. Eight years ago, a sleeping sickness that fed on traumatic memories threatened human civilization. Only a two-person team, diving into the stricken patient's mind, could cure it, and at great risk. The most skilled of these “divers” was Rune Winter, codename King, the only one who could cure the Sleep while leaving the patient's mind intact. Now the sickness is back, and this new strain can reinfect patients who've been cured. As the secret threatens to leak, King and his new partner, disabled Navy veteran Adam Garfield, have stumbled upon evidence that suggests the unimaginable: Did someone release this new Sleep deliberately? Omnibus edition includes Parts 3 and 4.
