Starcraft kindle books on sale today (10 Dec)... any good?
 

There's almost a dozen of the books in the Starcraft series included in today's kindle sale. Has anyone read any of these, are they any good? I generally like military Sci-Fi (Sweeney's Battle for the Solar System, Douglas's Star Carrier, Hicks's In Her Name and Currie's Odyssey One series to name a few). Does anyone know enough about the books on sale today to know if they are related to each other? It looks like there is a Dark Templar trilogy, and two in the Ghost series (it is unclear if/how they are related though).

TIA
