Do whatever you want, try not to be tempted to read The Luminaries. Booker prize or not, the book is too big, the plot is too ambitious and flawed which overshadow the excellent characterization and style.
Somebody mentioned Donna Tartt. I enjoyed The Secret History. The Goldfinch and The Little Friend are sitting on my shelf waiting to be read. I will definitely read the latter but don't feel much excitement for The Goldfinch.
