The phrase I was searching for throughout "Sailor Song" was "wish fulfillment." It's difficult to read the protagonist, Ike Sallas, as anything but the man hero that Kesey constructed in McMurphy of "One Flew over the Cuckoo's Nest," and really anything but a stand in for the agonized activist Kesey himself. I'm loathe to draw comparisons between authors and their subjects, but Ike Sallas is simply not a believable character, and if he's just a construct, well, then I guess that's the only option we've got.
There's going to be a lot of discussion of the ending of the book, a lot of angry confusion that at first gives you the sensation you're at the wrong end of a prank. But, in a strange way, the ending works in a novel about futility and failure. Sure, the book is merry enough along the way, with a wildly constructed future of Alaska featuring eternally burning garbage heaps, overweight Irishmen dancing with their own bellies, sudecitive/innocent "primitive beauties," high flying adventures against gargantuan mormons and pigs fighting bears. In fact, in many ways, the book works best simply as a prank or a joke - it's funny in the same ways that Benny Profane of "V" or Orin Incandenza of "Infinite Jest" are. But whereas both of those characters meandered through absurdity, they were always reigned within the confines of a novelistic purpose, even if not a personal one.
Which brings me back to failure. Ike Sallas was once a freedom fighter ala Cesar Chavez, and then calmed down some. We never really see any of this, except in peekaboo flashbacks and the odd grunt. But Ike's time is over. He's let his fire go out, and the eco-terrorists have lost. Temperatures soar across the globe, the wilderness is dying. Ike manages to rally once, firing off an impassioned speech against encroaching globalization on his Alaskan wilderness town, and he utterly fails, impressing no one and changing nothing. The point is, Ike's time is past. Kesey's time is past.
So when an event occurs in the last sixty pages of the book that renders all of Ike's struggles moot (some could say the ending is alluded to, but the novel has so many sidetracks and deadend turns it resembles the Alaskan coastline, so if we were to catch on to the impending events, it was either sloppy writing or an afterthought), it's almost understandable. The previous 460 pages were futile in the face of this catastrophe and accomplished nothing, just as Ike's efforts did nothing to stem the erosion of the environment, just as Kesey didn't stop oppressive elements in society.
To call this book a swan song would be going a bit far, I think. But Kesey was at least aware of the parallels he was creating between two tired warriors, embittered by their failures and doing their best to cling to their lovers and friends, their merry pranksters, waiting to overcome the ignorance of the masses in their wilderness shacks.
All in all, the book is a failure too. It entertains without saying anything, dangles characters and plot points like a hyperactive puppeteer more interested in his mental whispering than his audience. In a way you wonder if Kesey was trying to join his contemporary Pynchon in a postmodern examination of characters and themes, mixing pop songs and folk tales with emotional drama, ambassadors and bowling alleys, a sea of fishkids and a sea of lost refugees. And maybe, maybe he just realized he couldn't get there, and wanted us to remind us that this wasn't his fight anymore, and bowed out, wishing us a cackling 'good luck' on the future we made by ignoring his advice.
