Riding Out the Return - The Laura Harper Trilogy, #1

Should a mother hide the truth from her son, for his own good?   When her husband Jack has a freak training accident, Laura Harper is launched into the world of horses and in no time at all, the successful accountant is mesmerized by a little colt. Then the Harper couple suffer a big blow.  Jack's ex-girlfriend, Penny, is demanding he help her find their baby, whom she gave up eighteen years ago. That child is Laura's adoptive son, but she and Jack don't want to reveal that he is living with them.
The boy met Penny once and despises her. Discovering she's his birth mother will trigger his autoimmune disease - and scar him emotionally. But can Laura and Jack keep the information a secret? Or are they morally obliged to divulge the truth? As always, Father Michael is on hand to guide the family with humor and wisdom through their biggest challenge yet.
