Two realities. One captain. And a voyage beyond everything we thought we knew.

In this thrilling double-volume collection, Into the Alternate Universe / Contraband from Otherspace, A. Bertram Chandler plunges Captain John Grimes into the unknown—where the laws of physics twist, loyalties blur, and reality is dangerously negotiable. These two back-to-back science fiction adventures push the boundaries of space travel into the realm of speculative dimensions and multiversal mayhem.

In Into the Alternate Universe, Grimes and his crew embark on a seemingly routine mission that rapidly veers off course when a mysterious space warp hurls them into a parallel reality. There, familiar systems don’t exist, and mankind’s reach has taken a very different path. Can they find their way back—or will the temptations of this new universe change them forever?

In Contraband from Otherspace, the stakes grow even higher. A smuggler’s cargo from a different dimension starts to unravel the fragile balance of the known universe. Grimes must uncover what’s being transported, who’s behind it, and why this strange “contraband” holds the power to alter entire worlds. The moral lines between right, wrong, and what’s profitable are anything but clear.

With his trademark blend of sharp naval command, philosophical depth, and wry humor, Chandler crafts an unforgettable two-part odyssey. These are tales for fans of alternate realities, cosmic contraband, and captains who think with both heart and grit.
