Sword and Dagger was the first Battletech novel I read, back around 1990 or so, at just about the apex of my fandom. I hated it so much I didn't read another one until 1998. If I hadn't loved Stackpole's X-Wing books so much, I don't know if I'd have ever given anything else a chance. Fortunately for me, I worked at a Greenhouse that summer with 12 hour shifts and few customers after July, and I got the Warrior Trilogy from the nearby Waldenbooks.
Side note, I hated Sword and Dagger so much that I'd traded in to the local used book store for 1/2 cover price in store credit shortly after I got it. About 15 years later I got a used one off of Amazon for $40.
