Impetus of War (Battletech #30)

Plot

The mercenary Northwind Highlanders are recruited to take an enemy-held supply planet. But when they arrive, they find their intelligence reports worthless, and the planet heavily-fortified and guarded by elite "Mech warriors! Outgunned and out-numbered, the Highlanders are left with only one option--a desperate plan that could turn the tide, or leave them smoking hulks on the 'Mech-littered battlefield.
