Here is a little fact you don’t know about book 1 in the series. In the original draft of The Teacher’s Billionaire Helen Lee did not tell Callie about her father because she felt Callie’s should know the truth.  Rather Callie’s mom left two letters that Helen was to deliver after her death. One letter was to Callie telling her about her dad and the other was to Warren telling him about Callie.  Somewhere around the 3rd draft or so I changed to the way it reads now.
