This really isn’t a Solaris novel, as the title suggests. There are only a couple chapters on Solaris, the rest is a bog-standard “new mercenary company” story. A dispossessed Mechwarrior gets some Mechs and some pilots together, they find a bad contract and they somehow make it through. The novel is very much written as an intro to BattleTech, and it does that work competently. However, the characters are kind of bland and nothing important to the universe happens. If you’re going through old BT novels, I’d recommend skipping this one.
