A Sealed Chamber. A Hidden Fragment. A Truth They'll Stop at Nothing to Bury.
At seventeen, Ava Calloway can read a code no one else alive can: the Alexandria Cypher, built together with her father and shared with no one but the two of them.
Nothing could prepare her for where it leads; the discovery beneath Alexandria. A hidden chamber, untouched for centuries, holds a fragment tied to Mary Magdalene. For two thousand years, people have rewritten, debated, and deliberately suppressed the life of this figure. What Ava finds could shake the foundations of history itself. But some will do anything to ensure it never sees the light of day.
Drawn into a dangerous web of secrets is Marcus Visconti, heir to a lineage of scholars sworn to protect Christianity's most closely guarded truths. Together, Ava and Marcus unravel coded warnings, long-forgotten archives, and hidden manuscripts, racing across Egypt, Rome, and Switzerland.
For fans of Kate Mosse, Brad Meltzer, and Deborah Harkness, The Alexandria Cypher delivers a heart-pounding journey of mystery, history, and suspense.
