Ready Player One meets The Fault in Our Stars in this gripping blend of science fiction and fantasy about a couple's desperate attempt to hold onto one another against the greatest enemy of all.

An experimental new technology called the SynAPP, developed by the company Synerdyne for palliative care, allows users to enter a simulation generated directly in their minds. There patients escape to a virtual environment, dubbed Elysium, where they participate in a communal structured dream, experiencing a life free from injury, illness, and physical limitations.

Sam and Marcus, founding members of Synerdyne, have found another use for the SynAPP. Instead of the mundane and curated Elysium, they visit a gritty fantasy setting, affectionately called Sam's World, originally developed as part of Synerdyne's now-defunct entertainment division. It is a savage land, filled with danger and adventure, where Sam takes on the mantle of Morrigan the Barbarian. When visiting she escapes the cancer that has left her suffering and bedridden, interacting with Marcus as though nothing has changed in their relationship.
