Sharing Max by Holly C. Webb

Ella Cassidy had just one rule. Never let a guy pick her up in a bar.
That was until she met Nate. A chance meeting in a bar and Ella is completely swept off her feet by this handsome stranger, and she breaks her one golden rule.
However, the morning after the night before brings some surprising revelations, and Ella runs before she has to face what she has done.
But Ella soon finds out that she can’t run from all her problems when she is left with a permanent reminder of her one night stand. Her son, Max.
Max becomes the centre of Ella’s world and the one little piece of Nate that Ella will never lose.
When he is diagnosed with Autism, Ella is devastated, but she vows to give him the best life she can.
Just when Ella thinks that her and Max’s life is finally falling into place, Nate comes crashing back into their world and brings with him a whole load of new problems for Ella, and soon her world seems to be spinning out of control.
Can Ella and Nate find their happy ever after, or will Nate’s other life destroy Ella’s world forever?
Can she ever find happiness, Sharing Max?”
