BattleTech: Grey Watch Protocol (Book One of The Highlander Covenant), Paperback

In the 32nd century, the Republic of the Sphere is beset on all sides, its enemies seeking the most important weapon in the Inner Sphere: interstellar communication. As the forces of the Capellan Confederation advance toward the heart of the crumbling Republic, they are laser-focused on the one goal that will give them the upper hand and destroy the Republic once and for all: the planet of Northwind.

Homeworld of the famed Northwind Highlanders mercenaries, Northwind is not only the site of a century-old betrayal, it also boasts the only working hyperpulse generator along the line of the Confederation's advance. Sang-shao Lindsey Baxter and the Fourth McCarron's Armored Cavalry have been tasked with taking Northwind at all costs, and the besieged Republic is unable to lend further support to the defending XII Hastati Sentinels. Northwind will be easy pickings, and other sharks smell blood in the water. The Highlanders' honor remains strong, but will it be enough to survive the coming storm?
