Book Advent Calendar, Day 18: in which we are sick, and books I want under the tree

So my family have slowly succumbed to a virus this week.  A cold in one child, a sore throat and hoarseness, and chills in the other child.  Husband is now losing his voice.  And today I could feel it creeping in, the virus, making me move so slowly, and start to ache everywhere.  Throat sore....so no deep bookish thoughts or long post today, my dear readers.  Instead, my bookish advent calendar item for the day is a question to you, dear readers:  Is there a certain book or two that if you don't find under the tree this year, you will go out and buy in the new year?  If so, which book is it?  I'm curious to know what you are longing to read.  Myself, I'm really hoping to find The Martian by Andy Weir,
                               

and  The Fabled Coast:  Legends and Traditions from Around The Shores of Britain and Ireland by Sophia Kingshill and Jennifer Westwood.

 A third book I just discovered and REALLY want to read is The Clockwork Dagger by Beth Cato.  It's not on my list, I found it after I'd given my wish list to my husband.
                                    

So I suppose the question I am also posing to you is, should I tell him that I've found another book already I really want?

*****Edited to add:  I must be really sick, since I already blogged about wanting the first two books under the tree in an earlier advent calendar post!  lol  I suppose this post is about finding that last-minute book that you really like the look of, and is it too late to ask for it?
