Something along the lines of Becky Chambers' Wayfarers series (Small Angry Planet & sequels) or Ready Player One would be ideal - basically a good fun Christmas read.
Contemporary suggestions please - between me, ex-H and friends we have a large and wide ranging sci-fi/fantasy collection so with older books one of us will probably have them that she can borrow. She's enjoyed Ann Leckie, Adrian Tchaikovsky, Three Body Problem series, Dark Eden series, Gemsigns series etc so a fair mix.
Anyone read any good contemporary sci-fi recently that might fit the bill?
