Bookriot Read Harder Challenge 2015

This year I am going to tackle the Book Riot Read Harder challenge to expand my reading horizons.

There are only 24 tasks to complete and they are to read:

A book written by someone when they were under the age of 25

A book written by someone when they were over the age of 65

A collection of short stories (either by one person or an anthology by many people)

A book published by an indie press

A book by or about someone that identifies as LGBTQ

A book by a person whose gender is different from your own

A book that takes place in Asia

A book by an author from Africa

A book that is by or about someone from an indigenous culture (Native Americans, Aboriginals, etc.)

A microhistory

A YA novel

A sci-fi novel

A romance novel

A National Book Award, Man Booker Prize or Pulitzer Prize winner from the last decade

A book that is a retelling of a classic story (fairytale, Shakespearian play, classic novel, etc.)

An audiobook

A collection of poetry

A book that someone else has recommended to you

A book that was originally published in another language

A graphic novel, a graphic memoir or a collection of comics of any kind (Hi, have you met Panels?)

A book that you would consider a guilty pleasure (Read, and then realize that good entertainment is nothing to feel guilty over)

A book published before 1850

A book published this year

A self-improvement book (can be traditionally or non-traditionally considered “self-improvement”)

Sound like a challenge you would enjoy?
Which of these categories would you find the most challenging? For me I think it's the microhistory one.
Please comment if you have any suggestions of books to read for these categories.
