Now playing for Toulon in France, the fly-half amassed 112 caps for Wales before stepping away from international rugby in 2023.
Reflecting on his career in his upcoming book, Biggar says: "When I look back, I can confidently say I gave everything I had."
The book's synopsis reads: "Biggar has never fitted the mould. Throughout his long and decorated career, he has had to confront the critics, to silence the cynics.
"His playing style has been described as brash, aggressive and forthright, and it has earned him a reputation he has never been able to shake.
"But to anyone who knows him off the pitch, he is one of the most grounded ambassadors the game could ask for. "Honest and self-critical, Dan offers a rare insight into his personal and professional life. He talks candidly of his place within rugby, from the Premiership through to the Lions, and of the power dynamics within Wales’ most successful squad ever.
"He also opens the changing room doors and explores his relationships with past team mates, coaches and managers, from Warren Gatland and Shaun Edwards to Alun Wyn Jones and Wayne Pivac."
In a recent interview with TalkSport, Biggar confirmed he will not be available for the 2025 Lions tour.
"That chapter has closed for me," Biggar said. "When I retired from Wales, I thought I might miss it, but I haven’t. I'm really enjoying life in France and the media work I'm doing.
"If I had stepped away from Wales and missed it, things might have been different. But I feel it was the right time to move on."
Eight Players Who Flopped in the Six Nations This Weekend
The second round of the 2025 Six Nations saw Italy defeat Wales 22-15 in Rome, England edge France 26-25 at Twickenham, and Ireland secure a dominant 32-18 victory over Scotland at Murrayfield.
Despite the thrilling action, several players underperformed. Here’s a summary of the eight who struggled, with quotes from the key publications.

RUCK 5/10: "Couldn't get his nation ticking in the early stages."
The Scotsman: "Limited impact on the game early on as Ireland took control."
Verdict: Russell was underwhelming, leaving Scotland on the back foot from the start.
2. Jonny Gray (Scotland)
Rugby Pass 5/10: "Struggled to make an impact and was replaced early in the second half."

Rugby Pass 5/10: "Had a few sloppy passes and missed a try-scoring chance."
Mail Online 6/10: "Far from his best but still involved in setting up tries."

Wales Online 4/10: "Struggled in the lineout but solid in attack and defence."
