THE DARK TOWER CALLS by SILPIKA KALITA

In one of the series of the classic master stroke, The Dark Towers;
Roland Deschain, the protagonist, the bare survivor of the Battle of Jericho Hill,
Depicts his tell to a stranger, named Brown; a desert dweller,
About his return to the haunted ruins of Gilead,
His heroic adventures and battles with the ghosts and the mutants,
His friendship with a bumbler, and his intrepid encounter,
With the invisible Not-Men, he battled in a place called Kingstown:
So that he could rescue a naive girl named Susan from his evil clutches.

There goes a whole juggernauts of alchemy, plucky battles
Jugglery and valiant encounters with the horrid spectres.

Indeed, a magnum opus of time travel, epic wars, mystery
And sorcery to read and explore time and again!
