If the opening assault on Cologne Cathedral, the theft of the Magi relics, and the scramble through Vatican stacks hooked you, you’ll love how Angels & Demons plunges you into papal politics and secret societies. Like when Gray Pierce teams with Rachel Verona and consults Church scholars while dodging Seichan, Robert Langdon races against a literal countdown in Rome, decoding symbols in churches and archives as cardinals are targeted one by one. It’s that same blend of sacred history, high-stakes ritual, and breathless chase you enjoyed in Map of Bones.

You liked following Gray, Rachel, and the Vatican contacts as they pieced together alchemical hints from the stolen bones of the Magi. In The Templar Legacy, ex–agent Cotton Malone chases a trail of ciphers and manuscripts tied to the Knights Templar, moving from monastic libraries to ancient fortresses with the same code-cracking momentum. Where Map of Bones uses church history and hidden laboratories to unlock a deadly secret, this one layers manuscripts, caskets, and centuries-old riddles into an investigation that keeps tightening until the final reveal.

If the mass murder during Mass at Cologne and the frantic pursuit that hurled Gray Pierce across Europe and into Egypt got your pulse up, The Last Templar opens with a dramatic raid at the Met that ignites a relentless chase through crypts and deserts. Like Sigma’s race to decode clues from the Magi bones while the Guild and Seichan close in, archaeologist and FBI leads here juggle ancient codes, lethal pursuers, and revelations that upend what they thought they knew—at full throttle.

If you enjoyed the Sigma Force dynamic—Gray coordinating with scientists, soldiers, and Vatican allies while Seichan’s shadowy agenda complicates every move—Plague Ship gives you the Oregon crew: a tight-knit, gadget-loaded team taking on a bio-threat conspiracy. Much like the way Sigma splits up to chase leads from Rome’s archives to Egyptian ruins, this ensemble runs parallel ops that interlock at speed, delivering that same tactical teamwork and globe-spanning coordination you liked in Map of Bones.

In Map of Bones, the path from the Cologne Cathedral massacre to hidden chambers and desert tombs felt vast—leaping from European sanctuaries to Egyptian ruins while sifting secrets guarded since antiquity. Library of the Dead mirrors that scope: an FBI investigation intersects with a medieval monastery’s terrifying secret, and the narrative sweeps across timelines and continents. If Gray Pierce’s journey from Vatican corridors to ancient catacombs thrilled you, this one’s time-layered trail and global canvas will hit the same sweet spot.
