Let's make this birthday one to remember.

51 years old (Born on January 01, 1974)

Happy Birthday, Ally Carter! May your day be filled with more intrigue than a Gallagher Girls mission and smoother heists than Kat Bishop could ever dream up. You've given us countless adventures, witty banter, and characters we secretly wish were our best friends—thank you for making espionage seem like the coolest extracurricular activity.

Here's hoping this year brings even greater success (and fewer double-crosses) as you continue to captivate readers worldwide. Whether you're plotting another thrilling twist or simply enjoying cake without surveillance equipment hidden inside it, may today remind you how much joy you've brought into our lives.
