Condition is VG+ in a VG+ or better dustjacket: tight with slight tilt (less than 1/8"); the usual slight bumping to spine ends and also to bottom corner of front cover; age tanning is mild and uniform (consistent with its vintage); light overall wear. Dustjacket is unclipped with no tears and very light wear to back cover, with more to back inside flap.

That protector took most of any wear and has been discarded.

A late novel by Wilson Tucker: Ice & Iron. [I haven't read this, so I'm quoting from the jacket copy of a hardcover and the blurb-copy of the paperback]:

Across the globe a new ice age is encroaching. From Alberta to Ontario most of Canada is deserted, its people resettled in the southern United States and Mexico, while mile by mile, century by century, the glacier grinds down their former homes. Fisher Yann Highsmith is a scientist stationed, with a few colleagues, on the edge of the ice field, recording its relentless growth and the destruction of life in its path. In the midst of this barren landscape the team recovers a weird assortment of artifacts that seem to appear suddenly out of thin air, and Highsmith fits them together into a fantastic theory of another dimension. Then the search parties begin to find bodies out of time and place and Highsmith's history of parallel worlds becomes a chilling reality.
[from a pb blurb]:
Yann Highsmith had problems: recording the progress of the glaciers moving down over the Earth and destroying civilization; trying to seduce a beautiful polylibrarian with all the warmth of one of those glaciers, and the biggest problem was finding naked primitive bodies were raining from the sky - warrior corpses that looked as if they belonged to the Stone Age, but instead were part of a terrifying future to come. Then a live one turned up.
