Age of Unreason is the 26th eBook in the Star Trek: Starfleet Corps of Engineers series. It continues the reactions of the da Vinci crew following the aftermath of the catastrophic Galvan VI incident, where half of the ship's complement were killed.
While the ship continues to be repaired, Carol Abramowitz, Bart Faulwell, and Soloman try to prevent a civil war on Vrinda. Carol is asked to host the ceremony that will begin a truce between the two warring powers, a ceremony involving an expression of honest, naked emotion, something she has never been particularly comfortable doing, especially after the events of Galvan VI.
On the planet Vrinda, Lord Farhan Tanek discusses the future of the Vardan religion and its people with his advisor, Enzo Clyvans. Tanek plans to use a new weapon to annihilate the Nasnan, a rival religious sect and Tanek's political enemy. Clyvans decides that the ensuing civil war would be too catastrophic for the planet and attempts to get to a communications tower located within a Vardan temple. He is able to transmit a signal to Starfleet Headquarters just before a security guard kills him...
