Any multi-book compilation or single-volume omnibus edition of the trilogy composed of The Thousand Orcs, The Lone Drow, and The Two Swords. From the publisher's website (on the 2007 Gift Set):

When Drizzt believes that his friends have been killed, trampled under the feet of a rampaging horde of orcs, the Hunter takes over and the already dangerous dark elf goes feral. Alone in the wilderness against an enemy that outnumbers him thousands to one, the lone drow is the most dangerous being in the unforgiving mountains of the frigid North. But is he as dangerous to himself, as he is to the orcs in his sights?

This new gift set features all three of the hugely popular books in the Hunter’s Blades Trilogy: The Thousand Orcs, The Lone Drow, and The Two Swords.
