Prosperous: Chutes & Ladders - Prosperous, #1

In the year 2260, the Merchant Raitor Union governs space travel across all known galaxies. The motto of Merchant Raitor is to help establish safe trade routes and peace among the nations. However, there are some who want to destroy Merchant Raitor and anyone who opposes them. On Earth, Truman 'Tru' Barnett left his xeno-psychiatry practice to join Merchant Raitor and return to space in his father's ship, Prosperous.
When he unexpectedly is promoted to Captain, he is assigned a 9-month cargo stint with the most dysfunctional crew that Merchant Raitor has to offer. The stint becomes even more complicated when the ship's A. I. computer starts behaving erratically, he discovers there is a murderer on board, and his ship is targeted by the Terallians after he and his crew learn of the Emperor's plans to start a war with Merchant Raitor.
He begins to wonder if he and the crew will even get to their destination alive.
