Fatal Revenant is a fantasy novel by American writer Stephen R. Donaldson, the second book of The Last Chronicles of Thomas Covenant series.

Linden returns to Revelstone and accomplishes her immediate goal of cutting off the Demondim's access to a fragment of the Illearth Stone, but shortly afterward she is transported thousands of years into the Land's past by the forms of Thomas Covenant and Jeremiah.

The Insequent explains Linden's odd appearance and presence by dubbing her the first of the "Unfettered Ones", thus keeping the Law of Time intact.

Whilst Covenant and Jeremiah attempt to teleport the trio to Melenkurion Skyweir, the source of the Earthblood, Linden is separated from them, and finds herself lost amongst the ancient forest of Garroting Deep.

However, in the midst of her revelation, Covenant and Jeremiah contrive to instigate a confrontation between the Viles and Garroting Deep's Forestal, Caerroil Wildwood.

He attempts to wrest Linden's white gold ring and the Staff of Law from her, but the Mahdoubt intervenes and forces the Harrow's forbearance, at the cost of her sanity.

An army of Sandgorgons appears and enters the melee, turning the tide of battle in favour of Linden's company; Roger Covenant retreats, and the Harrow and Esmer vanish.

Here they first encounter one of the fiery serpent-like skurj; the company struggle to fight it, and Linden finds she is unable to channel sufficient power from her Staff of Law as a consequence of Kevin's Dirt.

With Longwrath imprisoned by his fellow Giants, the company encounters Esmer, who warns them that Kastenessen, his grandfather, has sent a pack of skurj to thwart Linden's attempt to recover the krill.

The Harrow tells Linden that he knows where Lord Foul is keeping Jeremiah, and that he will trade the knowledge for the white gold ring and the Staff of Law.

But Linden will not be turned aside and, as she approaches the krill, her Dead appear to her: Sunder, Hollian, Honninscrave, Cail, the Old Lords - but not Thomas Covenant himself.

With her newly acquired power, Linden enacts her secret desire and hidden intention; she resurrects Thomas Covenant, the only person she feels can help her in her quest to find Jeremiah and defeat the Despiser.

Infelice replies that with her use of extreme power, Linden Avery has roused the Worm of the World's End, endangering the Arch of Time itself and all life in the Land.
