In 1993, Sandra released a new version of "Maria Magdalena" with a techno arrangement and futuristic music video. The re-recording turned out to be a flop. Nonetheless, she sang on three songs on Enigma's next album, The Cross of Changes, including the hit single "Return to Innocence". While pregnant with twins, Sandra recorded and released Fading Shades in 1995. The album saw new writer-producer Jens Gad working alongside Michael Cretu and comprised mostly pop-orientated material. A cover version of "Nights in White Satin" by The Moody Blues was released as the first single, becoming one of Sandra's lowest-charting singles in Germany, although it was a hit in Israel. The album met a lukewarm commercial and critical reception, and the second single, "Won't Run Away", failed to chart. After giving birth to sons Nikita and Sebastian in a Munich hospital through Caesarean section in July 1995, Sandra decided to put her career on hold. However, the following year she participated in recording two songs for Enigma's third album. 1999 saw the release of My Favourites, a double disc album featuring remixes of Sandra's older songs and some of her favourite ballads. It was a success, charting within the top 20 in some European countries. A new version of "Secret Land" was released as a single, accompanied by a music video in which Sandra sported a shorter hairstyle. Her vocals again appeared in two songs on Enigma's 2000 album The Screen Behind the Mirror as well as the project's 2001 single "Turn Around". She released ballad "Forever" in 2001, which was a minor chart success in Germany. It foreshadowed her next studio album, The Wheel of Time, eventually released in spring 2002, after several delays. The album was a chart success and met a positive critical response, producing two more singles, "Such a Shame", originally performed by Talk Talk, and another ballad "I Close My Eyes". In 2003, the DVD The Complete History was released, featuring all of her music videos. The same year, Sandra contributed vocals for Enigma's Voyageur album, which would mark the last time she worked with the project. After several years' break, in 2006 Sandra teamed up with Swiss singer DJ BoBo for a duet "Secrets of Love" on his Greatest Hits album. The single was a big hit, reaching top 5 in Switzerland and top 20 in Germany. Sandra subsequently took up performing live again and began
