The Hidden Cipher by Rich Petrelli introduces The Templars Legacy Trilogy. This is a book that fans of Dan Brown will adore. The premise is compelling: a Templar codex, dating back centuries, contains secrets buried in the vaults in the Vatican that can change history as we know it. Cryptologist Dr. Elena Voss immediately understands the symbols and the danger they pose. As she races to unearth the truth, a mysterious network linked to the power that once destroyed the Templars goes after the fragments as well, and will destroy anything that stands in their way. Elena is joined by field operative Antoine Rousseau and researcher Liam Hayes on a hunt that takes them across Europe. Follow them on this pulsating journey as they race through cathedrals, ancient ruins, and crypts, trying to decode symbols and unearth secrets that have been kept hidden through blood and silence.

Rich Petrelli’s novel is an exhilarating ride, and I can’t wait to read the entire trilogy. You are immersed in a world similar to that of Dan Brown's Angels & Demons. Just when you are sure that the heroine has hit the jackpot, she is whisked away to something else. And as time passes, the danger grows stronger. The plot is complex and filled with action-packed scenes and suspense. I loved the gorgeous prose, the short chapters, the timely paragraph breaks, and the excellent writing that make the book even more enjoyable. The characterization in The Hidden Cipher is one of the exceptionally accomplished elements of the story, and Elena’s intelligence and curiosity were infectious. This book gets my vote on every level.
