About this title

Synopsis

Three hundred thousand climbers enter Level Three. The shapes have stopped being shapes. They are words now.

Ethan Vale ranked to Architect by learning to hold five dimensions in his head at once. He lost an architect named Obi on a rotating bridge and a physicist named Mira in a room made of mirrors. He received a message no one else could see, written in a handwriting that was not the Codex's own.

Now the Codex is testing something it has never tested before: language. The trials demand grammar, ciphers, substitution codes, and the ability to read a constructed language that someone designed from scratch. The three shapes — triangle, square, circle — are no longer patterns to be recognized. They are an alphabet to be decoded.

His team has grown. Lena, a computational linguist who survived Phase One by treating the Codex's instructions as a dead language. Dayo, a former GCHQ cryptographer who has spent six weeks alone in a maintenance shaft building a dictionary nobody asked him to build. Gideon, the old structural engineer whose body is failing but whose mind can still read a building faster than anyone alive. Sera, the physicist who sees math underneath everything. And Marcus, the man who was denied and returned and is no longer climbing — he is investigating.

Because someone wrote a letter on a wall the Codex doesn't monitor. Someone signed the Core Door in a language the system's own grammar cannot express. Someone took participants who were supposed to be dead and filed them under a different word.

The word is RETAINED.

And one of the names on the list is someone Ethan has been carrying since a grocery store aisle in Level One.

The Codex Trials: Level Three is the third book in a cognitive LitRPG series where the system doesn't reward strength — it rewards the one who keeps reading.
