Thanks for the suggestions so far!
I like many different genres. Thrillers, contemporary literature, memoirs, mystery, etc. Some of the books I've enjoyed recently besides The Goldfinch:
The Ocean at the End of the Lane by Neil Gaiman
Doctor Sleep by Stephen King
Gone Girl by Gillian Flynn
The Immortal Life of Henrietta Lacks by Rebecca Skloot
Wild by Cheryl Strayed
House of Tomorrow by Peter Bognani
North to the Night by Alvah Simon
Faithful Place by Tana French
I liked The Book Thief too, Kristin. Clara, And you are the second person I've seen mention Where'd You Go Bernadette? -- I will check that out!
Downloaded on my iPad, I have Khaled Hosseini's And the Mountains Echoed, Twelve Years a Slave, The Luminaries by Eleanor Catton, Skippy Dies by Paul Murray, and Sue Monk Kidd's The Invention of Wings. And no, even though I'm a pretty fast reader, I know I will not read all of those on the trip. I sort of "stock up" from time to time. But I know I need to take a paper-based book as well, for when the battery runs down on the iPad. I like to take something really engrossing on the plane.
I am also figuring out what movies or TV shows I should load up on for the flights as well! On my way to the Arctic I took I caught up on multiple seasons of The Wire.
