The invitation for Bahar and Ilkay's wedding was sent in the form of a bookmark in one of the Harlequin Romance series novels. In this way each invitation was unique as not one novel was the same. The bookmark goes:
"If we were to expain, it would be a novel. So instead, come to our wedding and share our happiness.
On the evening of the 19th of August, around 6 pm, at Sultansuyu.
Bahar & Ilkay"
