America's librarians announced their top children's book picks virtually on Monday – awarding the 2021 Newbery and Caldecott medals, among several other honors.

The John Newbery Medal for the most distinguished children's book in 2020 went to When You Trap A Tiger, by Tae Keller. The book's central character is a girl, Lily, whose family moves in with her dying grandmother — and a tiger from Korean folklore shows up looking for something that was stolen.

Former President Barack Obama's memoir A Promised Land, focusing on his political life from his time in Chicago through the killing of Osama bin Laden during his presidency, hits shelves Tuesday.

The book acts as a record of the former president's rise to the nation's top elected office — and his first two years on the job. But it also gives a window into his thinking along the way, about policy, his political life and his personal life.
