The eighth Briton killed in the Sri Lankan terror attack has been described by her husband as "a conduit for bringing people together to both make things happen, and make them better".
Lorraine Campbell (55) is believed to have been in Colombo on a work trip when she was among at least 359 people killed by a series of blasts at churches and hotels on Easter Sunday.
The IT specialist, originally from Manchester but who had been living in Dubai, was in the Cinnamon Grand Hotel when it was attacked.
Her husband Neil Evans said: "Lorraine was a real tour de force. She epitomised the qualities she lived by, and was a conduit for bringing people together to both make things happen, and make them better.
"I've lost my best friend in the world for all the adventures we shared and planned for the future.
"I, Lorraine's family and friends are in a state of disbelief and grief for what has happened and as such, would respectfully ask that our privacy at this difficult time is respected."
A statement from Ms Campbell's family added: "Lorraine, known to most people as Loz, was a woman who embraced life to the full, and meant so much to so many people and there will forever be an enormous void that will never now be filled.
"Loz was a wife, mother, sister and aunt, and a close friend to so many people, having risen through the ranks of the IT world, working in multiple cities in the UK and abroad."
Police in Colombo have detained 58 people in connection with the bombings, claimed by the Islamic State group, while specialist officers from the Metropolitan Police's Counter Terrorism Command have been sent to the country to support the bereaved and Scotland Yard has asked for images or video taken during the attacks.
It comes as officials in Sri Lanka claimed one of the suicide bombers may have studied in the UK.
Many of the attackers came from well-educated, middle-class families, and had been part of a pair of little-known extremist Muslim groups, Sri Lanka's junior defence minister Ruwan Wijewardene told reporters.
He added at least one had a law degree and some may have studied in the UK and Australia.
Mr Wijewardene distanced himself from suggestions that the bombings were revenge for the massacre at two mosques in Christchurch, New Zealand, last month, which killed 50 people.
He said there was no direct evidence to say the attacks were retaliatory.
In addition to the eight Britons who died, a locally employed British Council employee was "in hospital with his wife, both with serious injuries", said Foreign Secretary Jeremy Hunt.
Among the British victims were Anita Nicholson, her son Alex, 14, and daughter Annabel, 11, who died when one of seven suicide bombers struck as they ate breakfast at the Shangri-La hotel in Colombo.
Londoner Matthew Linsey's daughter Amelie (15) and son Daniel (19) were killed in the same blast on the final day of their holiday.
GP Sally Bradley and her husband Bill Harrop, a retired firefighter, from Manchester, died in the Cinnamon Grand Hotel bombing.
