Inebooks has released another Interactive Novel by the name of Shadow's Rage. I actually own a few of their other books, Lord of Blackskull Keep, Goblin Bane, Flame of the Illean, and To the Magickal Pond. These books are really great. They remind me of the old text based RPGs, except with pictures. Their newest addition is by the author of To the Magickal Pond.
Here is the introduction to the story (taken from Inebooks site):
A fire is loose in the streets. A fifty-foot tower crumbles into the town's market center, and huge blocks crash from it into the roofs of other buildings, burning everything to the ground. The thick smoke makes his eyes tear. A crackle of fire explodes nearby. But oddly, there is no one in sight - no one screaming in panic - nor is there any evidence of a responsible party.
The young man begins to think as his horse trots into the crumbled market center. In the past, trolls have attacked travelers outside Vandor, but only in interest of food. The Holikan dwarves came to sell their finely made weapons and armor.
Can you a mere squire discover what has destroyed your town?
Can you search out and be reunited with your master Markinson, the valiant Paladin?
In fact can you survive The Shadow's Rage?
More information can be found here. A demo is available as well.
If you are interested in reading about their other games/novels, PDA Buyer's guide has reviewed both Flame of Illean and Goblin Bane.
