Teleportasm by Joshua Millican

Four friends unearth a unique VHS tape that, when viewed, causes short-distance teleportation with euphoric after-effects, inadvertently launching a perilous trend.

As copies of the original tape are made, the results become less predictable and ultimately gruesome due to analog generational decay. Despite the danger, some will risk everything for just one more trip.

Part of the Killer VHS series of standalone novels from Shortwave Publishing - where movie monsters come to life and old VHS tapes summon long-buried evils. You'll probably survive, as long as you remember to be kind and rewind.
