Used book – An Unforgettable Summer, Darlene Gardner, Françoise Rigal

When Ryan passionately kisses her, Annie realizes they've crossed the line of the pact they made... While Annie believes she gave up the baby she had as a teenager for adoption, her own father confesses the unthinkable truth: because he didn't have the heart, back then, to part with his granddaughter, he secretly entrusted her to friends and never lost touch. Today, little Lindsey wants to meet her real parents... For Annie, it's a double shock: not only will she see her daughter, but she'll also have to tell Ryan, and therefore face him – Ryan, Lindsey's father, the boy who betrayed her when she loved him madly and whom she deliberately lost sight of. Their reunion will prove even more upsetting than she imagined: because Ryan, determined to spend time with his daughter before revealing he is her father, demands that Annie first introduce him to Lindsey as... the love of her life.
