Free excerpts: BEA Buzz Books.
From the YA description:
Excerpts you can read right now include new work from established giants of the field (Ellen Hopkins; Garth Nix; Scott Westerfeld), authors best-known for their adult books (Carl Hiaasen; Michael Perry; Ben Tripp; Meg Wolitzer), and genuine newsmakers—including the first of James Frey’s attention-getting Endgame trilogy, which will include interactive elements developed in association with Google’s Niantic Labs.
From the adult description:
Highly-anticipated debuts include multi-generational family epic We Are Not Ourselves by Matthew Thomas, featured on BEA’s own “buzz books” editors panel alongside another highly-touted debut set for publication in over 30 countries, Jessie Burton’s The Miniaturist. We have Nayomi Munaweera’s novel longlisted for the 2012 Man Asian Literary Prize, Island of a Thousand Mirrors, and Audrey Magee’s The Undertaking, already shortlisted for the Baileys Women’s Prize in Fiction.
Well-established authors such as Tana French, Marlon James, John Scalzi and W. Bruce Cameron are represented with new work, as are excerpts from the last books in two popular series from Lev Grossman and Deborah Harkness.
