AIDP: Las tierras huecas: BRPD: Hollow Earth & Other Stories Book

This picks up right after Hellboy leaves the BPRD after the events of Conqueror Worm. He no longer trusts the BPRD, leaving the remaining members Abe Sapien and Roger the Homunculus wondering if they should leave too. Firestarter Liz Sherman appears to Abe in a burst of fire pleading for help so Abe and Roge along with newcomer Johann head to Tibet to find her. The book is really well written, flashing back to each character's first meeting with Hellboy while they search under the earth for Liz. Ryan Sook gives the book a creepy, forbidding look that reminds me of the scene in The Fellowship of the Ring where the party troops through the Mines of Moria. There's a few other odds and ends featuring members of the BPRD. It's not until volume 3 that BPRD gets its own ongoing series.
