---- Chapter 1 My son had a raging fever. I cried and called my star doctor husband, but he was celebrating his first love's daughter's birthday. At 7 PM, my son Tyler's temperature shot up to 102.5° F, and his lips were turning a frightening shade of purple. Clutching him, my fingers trembled as I dialed Ethan's number for the tenth time. The call finally connected, but all I heard was Ethan's impatient voice. "Sarah, I'm busy. What is it?" "Tyler's fever is really high, his lips are turning blue, and he says his chest hurts and he can't breathe..." I choked back my sobs, but he cut me off before I could finish. ---- "Didn't I just check on him this morning?" Ethan interrupted. "It's just a common cold. Don't make such a big deal out of it. Just give him some fever reducer." "But his symptoms were much more serious ..."" "Sarah, I said it's a cold!" His voice grew sharper. "I have a very important, critical surgery soon. Don't bother me. I'm hanging up." The line went dead. Tyler weakly tugged on my sleeve. "Mommy, is Daddy saving people again?" I bit my lip and nodded. "Daddy's amazing. He's a superhero, right?" Tyler managed a weak smile. "Mommy, I'ma little cold. 1 feel so sick... Am I going to die?" I hugged him tighter, feeling his small body tremble. "Mommy's taking you to the hospital. Another doctor can help you there." ---- "But Daddy is the best doctor," Tyler said stubbornly. "Daddy said he has to save all the patients in the world. Mommy, please don't be mad at him, okay?" On the rain-slicked streets of Seattle, I ran, carrying Tyler in my arms, sprinting toward the hospital. His breathing grew more and more shallow, his little face flushed red from the fever. "Hang on, baby. Just hang on." In front of the emergency room, I collapsed onto a hard, cold chair, my hands clasped in prayer. "Sarah?" A familiar voice called my name. It was Dr. Williams, Ethan's colleague. "What are you doing here? Where's Ethan?" "He's in an emergency surgery," I answered mechanically. Dr. Williams frowned. "Surgery? Ethan took leave at 3 PM. Said he had something important to take care of." I felt the blood freeze in my veins. ---- Just then, a notification popped up on my phone. Ethan's first love, Isabella, had updated her Instagram. (Thank you, Uncle Ethan, for making Emma's 8th birthday so special! Having you here makes my daughter and me feel so safe and happy.) Posted: one hour ago. Ethan. I stared at the stinging name, my fingers shaking as I scrolled down, only to see two photos that hurt even more. In the first photo, Ethan was kneeling beside a pretty little girl, both of them beaming at a birthday cake. It was a gentle expression I hadn't seen on his face ina very, very long time. In the other photo, Ethan was spinning the girl, Emma, around, both of them laughing their hearts out. The comments were a flood of praise: "Ethan is such a perfect dad!" "Emma is so lucky to
