Not even the final installment of Cassandra Clare's popular Mortal Instruments series, City of Heavenly Fire (out May 27), could bump John Green's The Fault in Our Stars from the top spot on Apple's iBooks bestseller list. Clare landed at #2 for the week ended June 2, followed by Maya Angelou's I Know Why the Caged Bird Sings, hitting the list after Angelou's passing on May 28.
