Dear John - Nicholas Sparks

When John met Savannah, he knew he was ready to turn over a new leaf. Always the angry rebel, he had dropped out of school and enlisted in the Army, not knowing what else to do with his life. Then he meets Savannah. The attraction is mutual and quickly grows into the kind of love that leaves Savannah vowing to wait for John while he finishes his tour of duty.
What neither realises is that 9/11 will change everything, prompting John to re-enlist and fulfil what he feels is his duty to his country and fellow soldiers. And, sadly, as so often happens when lovers are young and separations are long, Savannah falls in love with someone else. 'Dear John...' the letter reads, and both their lives are changed forever.
Years later, when John returns to North Carolina, he must come to grips with the fact that Savannah, now married, is still the only one for him. Now John must make the hardest decision of his life...
