Last month, she revealed her cancer was terminal

The best-selling Irish author Emma Hannigan has died following a battle with cancer.

Breast Cancer Ireland confirmed the news this afternoon.

Her most recent novel Letters to my Daughters topped the Irish charts only last month.

In 2005, Emma discovered she had a cancer-carrying gene, and since then faced 10 cancer battles.

Speaking about her experiences with the disease, she wrote: "I have found a wonderful outlet in the form of writing. If I had never been ill, I may never have started writing books." 

In a blog post in February, she revealed the cancer was terminal.

She is survived by her husband Cian, son Sacha and daughter Kim.

Tributes were paid to Emma today across social media:
