<p style="margin-bottom: 1.2em;">In The Billionaire’s Sister Strikes Back, Catherine Sanderson is nine months pregnant and preparing to attend her little brother William’s wedding. She chooses to fly economy but books two seats to make the journey easier. Catherine even brings along a jar of William’s favorite pickles. She can’t wait to meet the lucky woman who is about to marry her baby brother, now the wealthiest man alive.</p> <p style="margin-bottom: 1.2em;">The trip turns ugly when Catherine encounters an entitled, overbearing mother named Linda and her spoiled son, Tommy. The trouble begins when Catherine refuses to give up the extra seat she paid for. Linda and Tommy bully her, twist what happened, and then accuse Catherine of injuring Tommy’s head. Their behavior grows so reckless that they nearly cause the plane to crash, putting every passenger’s life at risk.</p> <p style="margin-bottom: 1.2em;">Linda demands that the flight attendant and captain take Tommy to the hospital. Once there, Catherine meets Chloe—the so-called lucky woman engaged to William. Like Linda, Chloe takes one look at Catherine and assumes she is a broke loser. She accuses Catherine without knowing who she really is. That is when the billionaire’s sister finally strikes back.</p> <h4 style="font-size: 1.2em; font-weight: 700; line-height: 1.4; margin-top: 1.5em; margin-bottom: 1em;">Characters</h4> <h5 style="font-size: 1.05em; font-weight: 700; line-height: 1.4; margin-top: 1.2em; margin-bottom: 0.4em;">Catherine Sanderson</h5> <p style="margin-bottom: 1.2em;">Catherine Sanderson is the main female character and is expecting her baby at any moment.
