When single mom Serena Keegan finally gives in to her son's pleas for a pet, they decide that fish are the perfect option for their apartment lifestyle. They quickly discover that they have a lot to learn about their aquatic friends. Thankfully, Dalton's Aquariums and More! is there to help. The owners, identical twins Lance and Liam Dalton, both find themselves attracted to her. They are eager to provide her with the assistance she needs, for the pets and for more...personal matters. Serena's past experience with men has been less than stellar, and she worries she and her son will end up hurt. Despite these fears, she finds herself falling for the sexy store owners, whose talents extend well beyond business. But Liam has a past he hasn't told her about, and when Serena finds out, it threatens their growing love. Note: There is no sexual relationship or touching for titillation between or among siblings.
