Tongue Tied 2

After years of tension, friendship, and hilariously awkward sex, Callie and III finally gave into everything they'd been dancing around-but just as things seemed to settle, life hits them with something they never expected: a real pregnancy.

Now back in London under watchful eyes and management pressure, the two must navigate what it means to go from best friends and bandmates to full-on parents-in-the-making. III is still just as awkward, just as sarcastic, and still tries to make conversation during sex (because dirty talk is terrifying), but he's also more protective, more involved, and more in love than ever.

As tour life slows down and real life speeds up, the couple must confront fears, secrets, family drama, and each other's baggage-while trying to figure out what it means to build something permanent in a world built on chaos.

Messy, hilarious, painfully real, and full of heart, "Heartlines" is the next chapter in Callie and III's story-this time, with a baby on the way.
