60. The Dark Tower 7: The Dark Tower, by Stephen King.

This is the final book in the Dark Tower series, and it's one of the best ones. Slowly, the tet is made whole through some very fast-paced adventures and back-and-forth-ing through doors between the Keystone worlds. They save the Beam they are travelling on, then progress towards the Tower, on the home stretch of their journey. As in the beginning, so in the end: Roland enters the Tower alone.

I really liked the last book. It's very action-packed, with never a dull moment - something is always going on. I don't like some of the things that happen in it, but that's partially down to emotionally distressing events, and partially down to differing character interpretations. Susannah, particularly with Detta's influence, strikes me as someone that would see things out to the end regardless of the consequences, and I'm not sure that I liked the end to her story. It seemed too much like running away from the truth to me, especially since she knew it wasn't real. Eddie's, Oy's, and Jake's ends were well in line with the images of them I have in my heads, so even though they were sad events, I was able to accept them. Roland's end is puzzling, and answers barely any of the questions I had amassed up to that point (in fact, it added about two dozen extras) but it also seems quite fitting. He is the Wanderer, and I get the feeling that the health of the Tower itself might, in part, be reliant on experiences brought to it by the line of Eld, which is at this time just Roland out in the world (and the Crimson King). It's a puzzle, and I don't think we'll get a clear answer, but it's interesting to contemplate.

As for Beam information, Gan's Beam is Elephant to Wolf.  Eagle to Lion was the beam snapped while the tet was in the Callas.

Finally in this last book, Walter is further explained. Walter answers only to the Crimson King, he is his second-in-command, but he has his own designs upon the Tower. Planning to kill Mordred and enter the tower himself, he is killed. Book seven does tell us that he served Farson, as opposed to WAS Farson, which I think is slightly contradictory to an earlier book. Roland pushes Walter on even as Walter pushes Roland. It's confirmed again that Walter is Flagg under an alias, and that he did not die at the end of The Gunslinger, but placed bones in his robe to fool him.Also confirmed again that Marten is another alias. We learn that Walter Padick was his first name, when he was a farm-boy in Delain. Interesting to see that Walter, the spectre that has haunted the story from the very first words, is not evil, is not black-hearted and bad, he is a more or less ordinary person that fell upon hard times and acted accordingly.
