Author Nina Walker & Grace Costello

ninawalkerbooks@gmail.com

Hi! I’m USA Today Bestselling author Nina Walker and I write YA & NA across multiple genres. Most of my ebooks are currently enrolled in Kindle Unlimited but New World Shifters and Vampires & Vices are offered at a discount on my coauthor’s website, which is the first link below.

And if you scroll down, you’ll find my adult
contemporary romance pen name, Grace Costello. Those books are all in KU.

I also offer signed books on TikTok Shop (while supplies lasts, they go fast) as well omnibus paperbacks and ebook boxsets on Amazon and my coauthor’s website.

I love writing and as long as you continue to love what I read, I’ll never stop creating more stories for you to enjoy.

XO,
Nina
