IF she can dream.". However, she said that nothing had not been put down as yet and that she and her co-writer, Allen, were simply playing around with different ideas. On October 18 2010, Duff posted on Twitter about a sequel: "Can't believe so many people have read the book already! Yipeeee! Starting the next one in two weeks".Devoted, hit the book shelves on October 11, 2011.

The Everly Brothers, Don and Phil; born Isaac Donald "Don" Everly on February 1, 1937 and Phillip "Phil" Everly on January 19, 1939, are country-influenced rock and roll performers, known for steel-string guitar playing and close harmony singing. The group was elected to the Rock & Roll Hall of Fame in 1986.

Don and Phil Everly are both guitarists and use vocal harmony mostly based on parallel thirds. With this, each line can often stand on its own as a melody line. This is in contrast to classic harmony lines which, while working well alongside the melody, are not as melodic by themselves.

For most of their recordings, Don sings the lower harmony part, while Phil takes the higher. One exception is on "Devoted To You". Although Don is still low and Phil is high, they switch lead and harmony back and forth. Don almost always sings any lines that are sung solo (for example, the verses of "Bye Bye Love".) Among the exceptions to this rule is the Everlys' 1965 single "It's All Over", where Phil sings the song's solo lines.
