TRIBUTES have poured in for a "fantastic mother" from High Wycombe who died following a car collision, aged 27, on Tuesday.
Marta Johnston lived in Sands with her five-year-old son, Brandon.
The third year Bucks New University student was driving to a charity meeting on Monday morning when her black Ford Focus collided with a black VW Golf.
Police were called to the collision at 9.50am on the A329 between Great Milton and Stadhampton.
Marta was taken to John Radcliffe Hospital but died on Tuesday.
Her boyfriend, James Elliott, said: "Marta was a fantastic mother to Brandon.
"She was passionate about being a mum. She always put Brandon before anyone and she would do anything for him.
"She gave him anything he needed and more. He couldn't have wished for a better mother."
Marta's Facebook page is full of tributes from friends and family.
Sarah Howson said: "Marta was such a fun loving, beautiful, strong woman and an amazing mother."
While Emma Louise Ferguson said: "Not only are you beautiful on the outside but you have one of the most beautiful souls I have ever met."
Marta moved to London from Poland when she was 18, and later moved to High Wycombe.
James, 42, from Wheeler End had been with Marta for two years. He said: "I was incredibly lucky to meet her. I am very honoured to have had a very short but fantastic time with her. She will be dearly missed by me and all of my family.
"She was pretty on the outside, as well as the inside. It is absolutely devastating.
"We were very much in love but Brandon came first completely. I can't emphasise enough what a brilliant mum she was."
He said she was very adventurous, friendly and out going. She was learning to play golf, go clay pigeon shooting and loved paragliding.
She spoke fluent English, Russian and German, as well as her native tongue, Polish.
Her parents, Jaroslaw and Barbara Uchal, came over on Tuesday morning from Poland to say their goodbyes.
James added: "She was an unbelievable girl- always smiling and happy and always put other people before herself- she always helped where she could.
"She was extremely bubbly and had a presence about her whenever she was in the room- everyone knew she was there."
Marta was in her third year at BNU studying Psychology.
He said: "She had some fantastic friends at uni. They were incredibly supportive and Marta adored them to bits.
"She loved uni. She was a very hard worker."
Marta had just finished her dissertation on Sunday night.
Piers Worth, head of the academic department of Psychology at BNU, said: "The first and most important thing we would wish to express is heartfelt condolences to Marta’s parents and her boyfriend.
"Students and staff are devastated and deeply sad at this news. We are a small department and Marta was a strong presence.
"I taught her for two years and found her determined to learn. Marta engaged with the subjects, talked about them, questioned them, pressed to understand and learn. If she didn’t understand something or agree with it, she had the confidence to make me explain until she could. There were some subjects Marta was unsettled or nervous of, yet she had the courage to keep going with them regardless. She was determined to do well and succeed. One of my colleagues described this as vibrant.
"She also had the humour to tease me during the teaching and make the work enjoyable as well as serious. All this tells you how important her studies were to Marta, and the end of this year will be so different without her.
"Our hearts are with her family and friends."
Marta's funeral is on April 24 at 2.30pm at the Chilterns Crematorium in Amersham.
